Day 6 - Acceleration - SU/SD

The speedometer on your car measures

• average speed.
• average velocity
• instantaneous speed.
• instantaneous velocity.

Acceleration is the

• slope of a position-time graph.
• the area underneath a position-time graph.
• the area underneath a velocity-time graph.
• slope of a velocity-time graph.

Average acceleration is the change in velocity over a given interval of time.

• True
• False

Acceleration: is the rate of change in ___________.

• speed
• distance
• velocity 
• displacement 

_____ is/are measured in units of m/s² in Physics.

• Speed and velocity
• Distance and displacement
• Acceleration
• Vectors
