increase its mass and increase the force acting on it

Question 12

James is trying to prove Newton's 2nd law of motion. He tries to move 4 different objects with different masses, shapes, and sizes from one point to another. The objects are a toy car, a real car, a refrigerator, and a kitchen table. After some experimentation, he finds that force is dependent on the mass of the object rather than the shape. The object that takes the most force to move is the ________.

Accepted Answer

real car

Answer

toy car

Answer

table

Answer

refrigerator
