The terms velocity, speed, and acceleration are all very important concepts in physics. They all mean separate things and they have their own conceptual ideas, however they are also very similar. Velocity, speed, and acceleration are all rates of time, but two of them are vectors and one is a scalar, they are all physics concepts, but only one can be positive. Velocity, speed, and acceleration are all separate terms, so what did they mean? Velocity; the measurement of a rate of motion (speed) of an object in a certain direction, it changes when speed and direction changes. To find the average velocity you use the equation; Vav=Δx/Δt, and to find the final velocity you use the equation vf = vi + at. Speed is the rate at which an object can move, and to find the average speed of an object you use the equation Sav=distance/time. Acceleration is the rate of velocity changing with time, it also changes when the speed and direction of an object changes. To find the average acceleration of an object you use the equation Aav=Δv/Δt. …show more content…
First, they all are rates of motion which means that they all are measurable concepts that describe the real world. Also they all use some form of m/s, acceleration uses m/s2, and velocity and speed us m/s. An example of the terms used in a problem is; a bat is flying at a speed of 4 m/s but accelerates to 7 m/s when it sees a bug, what is the final velocity of the bat? use the equation Vf= Vi+at. Likewise they all have differences too. Speed is the only one of the terms that can be positive because velocity and acceleration can have directions that are positive or negative, or in velocity's case it can go in a north, south, east, and west direction. Secondly, human bodies can only feel acceleration and not velocity and speed. Finally, velocity, speed, and acceleration are all found using different equations or ways. Contrasting
The definition of a projectile is an object that the only force acting on it is gravity. Projectile motion is the path the projectile takes. We saw and used this topic a few times in our project. The first time we saw it was when the marble was flew out of the pipe and was in the air. The second time we used the topic to make sure the trains fell on the lever in the correct spot so the golf ball would roll. The third time it was used, was when the board fall on the balloon. It fell as half of a parabola since it started standing up.
When the eggs are dropped onto the pillow, the eggs will bounce a little and stay whole.
At the core of Newtonian physics was the fact that space and time were absolute. Newton’s absolute space was the space of everyday experience with its three dimensions: east-west, north-south, and up-down. This space gives us our sense of length, breadth, and height; according to Newton. We all, regardless of our motion, will agree on the length, breadth, and height of an object, so long as we make sufficiently accurate measurements. Newton’s absolute time was the time that flows inexorably forward as we age. It is a time whose flow is experienced in common by all humanity.
The purpose of the projectile lab is to test the validity of the law of conservation of energy. The application of this law to our everyday lives is a surprisingly complicated process. Conservation of energy states that energy cannot be created or destroyed, but that it can be transferred from one form to another. Consider the projectile lab from document A that this essay is based upon. In an ideal experiment, the projectile is isolated from everything except the gravitational field. In this case, the only force acting on the particle is gravity and there are only two forms of energy that are of interest: the energy of the particle due to its motion (defined as kinetic
The acceleration of a body or object is directly proportional to the net force acting on the body or object and is inversely
Rate is determined on how fast something is being consumed in a reaction, or how
The application of force on an object causes an acceleration of that object. Yet, force is not the only factor in the movement, or acceleration of an object. The two main influences on the acceleration of an object are net force and mass. For example, net force is directly proportional to acceleration while mass is inversely proportional to acceleration. Other factors such as the friction, air or fluid resistance, and pressure effect the acceleration as well. All of these factors do not work against or in accordance with acceleration in the same way. Friction works in opposition to acceleration. Friction involves two objects that are in direct contact with on another but are moving in different directions. Involved with friction is air and fluid resistance. Fluid resistance, such as liquids or gases, focuses on when the object is moving in the opposite direction of a fluid flow or through a dense area of fluid. Air resistance involves movement through the air. The most noticeable effect of air resistance is when and object travels into a strong breeze or wind. And finally pressure, pressure refers to an applied force. With pressure you will find that the overall weight of and object doesn’t change no matter how you stand or lay it but you will feel more pressure from that same object depending on the force compared to the amount of surface area. The weight of the object

The acceleration of a body or object is directly proportional to the net force acting on the body or object and is inversely proportional to its mass. (F=ma)(Newman)
One of the many reasons why time is not tangible is due to the fundamental properties of time.There are 3 main properties associated with time and these are a present moment that is special; some kind of flow or passage; and an absolute direction. These
Chemical kinetics is the study and examination of chemical reactions regarding re-arrangement of atoms, reaction rates, effect of various variables, and more. Chemical reaction rates, are the rates of change in amounts or concentrations of either products or reactants. Concentration of solutions, surface area, catalysts, temperature and the nature of reactants are all factors that can influence a rate of reaction. Increasing the concentration of a solution allows the rate of reaction to increase because highly concentrated solutions have more molecules and as a result the molecules collide faster. Surface area also affects a
Chemical Kinetics is the branch of chemistry that studies the speed at which a chemical reaction occur and the factor that influence this speed. What is meant by the speed of a reaction is the rate at which the concentrations of reactants and products change within a time period. Some reactions occur almost instantaneously, while others take days or years. Chemical kinetics understanding I used in the process of designing drugs, controlling pollution and the processing of food. Most of the time chemical kinetics is used to speed or to increase the rate of a reaction rather than to maximize the amount of product. The rate of a reaction is often expressed in terms of change in concentration (Δ [ ]) per unit of time (Δ t). We can measure the rate of a reaction by monitoring either the decrease in concentration (molarity) of the reactant or the increase in the product concentration.
One vital process in the human body observed in chemistry is the idea of chemical kinetics. Chemical kinetics is the study of the rate of reactions, or how fast reactions occur.1 Three factors that affect chemical kinetics are concentration, temperature, and catalysis. As the concentration of a substance increases, the rate of the reaction also increases.1 This relationship is valid because when more of a substance is added in a reaction, it increases the likelihood that the
Kinetic energy is the energy of motion. There are three forms of kinetic energy: vibrational, rotational, and translational. First, translational kinetic energy, the amount of translational kinetic energy that an object has depends upon two variables: the mass of the object and the speed of the object. Second, rotational kinetic energy, or angular kinetic energy, is kinetic energy. The rotation of an object is part of its total kinetic energy, looking at rotational energy separately around an object's axis of rotation. Vibrational kinetic energy is the kinetic energy an object because of
