IV.Observations

The more force we apply on an object, the faster an object goes. •The more mass an object has, the more difficult it is to change its state of motion. •Though the second attempt has more mass, it still has the same acceleration as the first one. •Air resistance from ceiling fan also affects the force to an object.

V.Conclusion

We therefore conclude that when the force applied to the object increased, the acceleration also increased, and that the mass of an object is inversely proportional to acceleration. We also conclude that the mass in the cart affects the force within it as it moves towards one of the road block. Also the friction between the cart and the track affects the force and acceleration. When the cart has a large amount of mass, then the cart will slowly move towards the road block but when the hanger has a large amount of mass in it then it will make the cart accelerate faster.

VI. Questions and Problems:
1.Did the results of this experiment verify that F = ma?
-Yes, because the net force is directly proportional to mass and acceleration. Also as we see in the experiment, the mass will help the cart accelerate faster if it has a small amount of mass but if the mass on the cart is large then it will make the cart to move slowly.

2.Why must the mass in F...
