Acceleration

Acceleration: is the rate of change in ___________.

• speed
• distance
• velocity 
• displacement 

Describe the motion of the car.

• The car has acceleration because it is at rest 
• The car does not have acceleration because it is at rest 
• The car has velocity because it is at rest 
• The car has acceleration because it is at rest 

A bus is moving on horizontal road in straight line. Determine in which of the following cases the bus is speeding up? 

• The bus changes its velocity from 20 m/s to 15 m/s.
• The bus changes its velocity from -20 m/s to -10 m/s
• The bus changes its velocity from 0 m/s to 20 m/s
• The bus changes its velocity from -15 m/s to 0 m/s

In each of the following cases, determine where the car has no acceleration ?

• A car shortly after a stoplight turns green.
• A car approaching a red light
• A car with the cruise control set at 80 km/h
• A car turning a curve at a constant speed

Determine the motion of the car ?

• Speeding up
• slowing down
• at rest
• constant velocity
