Question

2 which is the best example of newtons first law of motion? a a soccer ball remains motionless until it is kicked by a player. b a basketball is thrown in the air falls to the ground. c a baseball player swings at an approaching ball. d an ice skater pushes off from a wall and moves backwards.

Explanation:

Newton's first law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. A soccer - ball being motionless until kicked shows an object at rest staying at rest until a force (the kick) acts on it. Option B is an example of gravity (Newton's second law in the context of free - fall), option C is about applying a force to change the motion of the ball, and option D is an example of Newton's third law (action - reaction).

Answer:

A. A soccer ball remains motionless until it is kicked by a player.
