Intro to Forces and Newton's Law of Motion

What is a PUSH or PULL of an object?

• Motion
• Force
• Friction
• Gravity

Why is it harder for the boy in Image B to get down the hill?

• Motion
• Friction
• Work
• Displacement

If these boys are pulling with the exact same amount of force. What will happen?

• The boy in blue will win.

• They will not move at all.

• The boy in red will win.

• Both will fall down.

Which force produces a change in motion?

• unbalanced force
• balanced force
• gravitational force
• frictional force

It takes more force to accelerate the iron man on the left than the iron man on the right because the iron man on the left has more mass. This best describes

• Newton's first law, the law of inertia
• Newton's second law, the law of acceleration
• Newton's third law, the law of action reaction 
• The law of universal gravitation

The formula 
? = mass x acceleration
or 
? = m x a 
is used to find 

• Force
• Velocity
• Momentum
• Gravity

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