Velocity & Acceleration Review Adv

Acceleration occurs when an object changes its ______________ over time

• displacement

• velocity

• position

• mass

This is a velocity-time graph. Describe the motion of the object in line A.

• Positive acceleration

• Negative acceleration

• Constant Velocity

• Not moving

This is a velocity-time graph. What is the object doing in segment B?

• Positive acceleration

• Negative acceleration

• Constant Velocity

• Not moving

This is a velocity-time graph. What is acceleration of the object at segment A?

• 1 m/s

• 1 m/s²

• 2 m/s

• 2 m/s²

Why is the acceleration at point B zero? Select all that apply.

• the slope of a flat line is zero.

• the object is at rest

• the position is increasing at a linear rate

• constant velocity implies no acceleration

Describe the velocity for line B.

• increasing

• decreasing

• constant

• at rest

Describe the velocity for line C.

• positive

• negative

• constant

• at rest

Describe the position graph for line A.

• increasing, quadratic

• increasing, linear

• kinda straight

• at rest

Describe the position graph for line B.

• increasing, quadratic

• increasing, linear

• looks flat

• at rest
