Velocity - Time Graphs and Newtons Laws

What segment of the graph shows no motion, or standing still?

• A - B

• B - C

• C - D

• None

Describe the motion from B - C.

• Standing still

• Constant velocity of 60 m/min

• Constant velocity of 0 m/min

• Accelerating

Which is newtons first law states

• An object at rest will remain at rest unless a force is applied

• An object is moving

• An object has stopped

• An moving object will keep going when a force is applied to it

The tendency of objects to resist a change in motion is called:

• Friction

• Inertia

• Gravity

• Velocity

What are the appropriate units to describe acceleration?

• m/s
• m/s²
• cm
• there are no units associated with acceleration

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
