Question/Purpose: What happens to the effort force required to move the cart up the inclined plane if the angle of the incline is increased? Hypothesis: If the angle of the inclined plane is increased, then the effort force required to move the cart up the incline increases because as the cart gets dragged higher and higher up the inclined plane, the more gravity acts upon it. Controlled Variables: • Load force • Effort distance (30cm) Manipulated/Independent Variable: • Angle of incline Responding/Dependent Variable: • Effort force Materials: • 1-peg board • 1-cart • 1-inclined plane/ramp • 1-Newton Scale • 1-protractor • 1-large metal hook • 1-meter stick Procedure: 1. Place the pegboard upright and connect the ramp to the pegboard using …show more content…
The average effort force needed to drag the cart up the 10˚ angle of incline was .36N, and the average effort force needed for the 12˚ angle of incline was .56N. The average effort force needed to drag the cart up the 14˚ angle of incline was .66N, and the average effort force needed for the 16˚ angle of incline was .7N. The average effort force needed to drag the cart up the 18˚ angle of incline was .82N, and the average effort force needed for the 20˚ incline was .96N. Inclined Planes states, “If you make the ramp steeper, you’ll have a shorter distance, but it will be harder to push the rock (you’ll need more force). If you make the ramp less steep, it will have to be longer, but it will be easier to push. Either way, it’s the same amount of work in the end, but you have the choice of easier work for a longer time, or do harder work for a shorter time.” The evidence supports the claim because when the cart gets higher and higher off the ground the more gravity acts upon it, pulling it towards the centers of the earth. That causes there to be more force needed to pull the cart up the incline and act against the force of gravity. For example, the difference of the average effort force needed for the 10˚ angle of incline (.36N) and the average effort force needed for the 20˚ angle of incline (.96N) is .6N, supporting
Then I attached the “steps” to the milk crate. The steps will hold the base of the ratapult at a 25-degree angle. I attached the “steps” by drilling holes in the bottom of them and then tying them to the milk crate. Then I nailed the board with wallpaper into the back end of the base. The base was then nailed into the “steps”, and glued grass decorations and cardboard cows to the base. The ratapult was completed.
· To make sure the ramp does not slip I could put a door stop or wedge

friction, affecting the speed and distance the ball rolls. Title: The Effects of Height, Length, Surface, Weight, Size, and Material on the Distance a Ball Rolls Down a Ramp Aim: The aim of this experiment is to investigate the factors that affect the distance a ball rolls when released from the top of a ramp. Variables:
Two factors contribute to the resistive frictional force; a normal force and the friction coefficient. The normal force is the force holding the person up keeping them from falling towards the center of the earth. On level ground the normal force acts straight up against the acceleration of gravity. On a slope, the normal force is equal to the force of gravity proportional to the cosine of the angle of the slope to horizontal. This portion of gravity attempts to accelerate the person toward the center of the earth, the normal force resists this acceleration. The remaining component of gravity accelerates the body down the hill parallel to the slope, a linear acceleration.
(b), there is maximum kinetic energy and little potential energy. The kinetic energy propels the train up the second hill

In the experiment these materials were used in the following ways. A piece of Veneer wood was used as the surface to pull the object over. Placed on top of this was a rectangular wood block weighing 0.148-kg (1.45 N/ 9.80 m/s/s). A string was attached to the wood block and then a loop was made at the end of the string so a Newton scale could be attached to determine the force. The block was placed on the Veneer and drug for about 0.6 m at a constant speed to determine the force needed to pull the block at a constant speed. The force was read off of the Newton scale, this was difficult because the scale was in motion pulling the object. To increase the mass weights were placed on the top of the ...
The track we have to carry is long and hard. We have to build 4 curved track right next to each other. Four people have to carry a rail and one person putting in the spike with a sledge hammer in 3 strikes on the first spike. Most people working on the curve were Irish immigrants just like me. The track that we are laying is a seven feet by one feet. And four people have to carry the
Newton’s 2nd Law of Motion states that acceleration is directly proportional to net force when mass is constant. This experiment dealing with variable forces has as its objective the verification of this law. In this experiment this law is tested for verification in straight forward way. Through the use of a Force Sensor and an Accelerometer, data collection of observations and measurements that a force exerts on a small cart along with the cart’s accelerations are to be determined. The sensors’ measurements will be employed to give meaningful relationships between the net force on the cart, its mass, and its acceleration under these conditions. The resultant measurements revealed will verify and determine the force and acceleration relationship as stated by Newton.
This experiment could have been more accurate if the angle of the slope could have been lowered to stop the trolley from accelerating. The experiment could have also been improved by taking greater care in making sure that the weights didn’t fall off of the trolley after they collided with the trolley. Better weights should have been found for the 1.5kg as the ones used had to be tied together to reach the sufficient weight, thus making them more likely to fall off the trolley. Conclusion: The hypothesis was proven correct for the 500g weight, however, the hypothesis was not proven correct for the 1kg and 1.5kg weights as the momentum before the collision did not equal to the momentum after the collision.
