laws of Motion

An object at rest will _______ if no outside forces are applied.

• Stay at rest
• Increase Velocity
• Decrease Mass

A greater applied force is required to move an object with a greater mass than one with a smaller mass.

• True
• False

Acceleration is caused by a force acting on a mass.

• Newton’s first law of motion
• Newton’s second law of motion
• Newton’s third law of motion

For a force on an object there is an equal and opposite force.

• Newton’s first law of motion
• Newton’s second law of motion
• Newton’s third law of motion

Without any force to change it, an object at rest stays at rest and an object in motion stays in motion

• Newton’s first law of motion
• Newton’s second law of motion
• Newton’s third law of motion

In order to be ____ forces, their effects must cancel each other out and not cause a change in an object's motion.

• balanced
• strong
• weak
• normal

If the forces acting on an object are unbalanced, the net force is NOT ____.

• normal
• strong
• weak
• zero

Forces always act in equal and opposite pairs.

• Newton's 1st Law
• Newton's 3rd Law

What force slows objects down and keeps them from moving?

• Friction
• Acceleration

If there is a big mass, it would need a stronger force to accelerate it.  Which law does this describe?

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
