Question

James is trying to prove Newton's 2nd law of motion. He tries to move four different objects with different masses, shapes, and sizes from point A to point B. The objects are a toy car, a car, a refrigerator, and a kitchen table. After some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. The object that takes the most force to move is the

Answer 1

The car is the heaviest object there and mass is proportional to force, meaning the heavier it is the bigger the force should be in order to move it.

Answer 2

Answer:

A car

Explanation:

Newton’s second law of motion states that the rate of change of linear momentum is directly proportional to the applied unbalanced force. It also gives the measure of force i.e.

F = m.a.... (1)

Where

m is the mass of body

a is the acceleration produced

In this case, James is trying to prove Newton's 2nd law of motion. He moves four object namely, a toy car, a car, a refrigerator, and a kitchen table with different masses, shapes, and sizes from point A to point B.

It is clear from equation (1), that the force depend only on the mass of body not on its shape and size.

So, the force that takes the most force to move is ''a car'' due to its more mass.
