Newton's Laws

Newton's Law of Inertia (first law) describes the motion of:

Which law best explains why people remain in motion when a car crashes, if they are not wearing a seat belt? Options: Law of Inertia, Law of Acceleration, Law of Action - Reaction, Law of Gravitation

Which law best explains why more force must be applied to the bowling ball to make it accelerate at the same rate as the tennis ball? Options: Law of Inertia, Law of Acceleration, Law of Action - Reaction, Law of Gravitation

For every action, there is an equal and opposite reaction.

What is Newton's 2nd law of motion?

Which force causes an object to speed up or slow down (accelerate or decelerate)?

267.5 N unbalanced force applied to push a stuffed chair across the room, causing an acceleration of 4.2 m/s². What is the mass of the chair?

A net force of 15 N is exerted on an encyclopedia to cause it to accelerate at a rate of 5 m/s². Determine the mass of the encyclopedia?

Force necessary to accelerate a 1785 kg car at 50 m/s²?

Unbalanced force on a boy and his skateboard if total mass is 62 kg and acceleration is 0.36 m/s/s forward?
