What kind of force causes objects to move?

• Balanced

• Unbalanced

If a car is traveling at 60 m/s and speeds up to 80 m/s in a 10 second time frame... what is acceleration?

• 2 m/s2

• 2 m/s

• -2 m/s

• -2 m/s2

A car going 70 m/s slows down to 40 m/s in 10 seconds. Calculate the acceleration.

• 3 m/s2

• -3 m/s2

• 3 m/s

• -3 m/s

States that force equals mass x acceleration

• Newtons 1st law

• Newtons 2nd law

• Newtons 3rd law

Claims if an object exerts a force on another object, the second object exerts a force of equal strenght in the opposite direction back towards the first object

• Newtons 1st law

• Newtons 2nd law

• Newtons 3rd law

States an object at rest will remain at rest unless acted on by an unbalanced force

• Newtons 1st law

• Newtons 2nd law

• Newtons 3rd law

If these boys are pulling with the 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.

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

• 1st
• 2nd
• 3rd
