Velocity and Acceleration

An object travels 5 meters in the 1st second of travel, 5 meters during the 2nd second of travel, and 5 meters during the 3rd second. Its velocity is:

• constant
• decreasing
• increasing
• changing

An object is undergoing a constant acceleration. If the rate of acceleration is larger, the velocity reached after a given time interval will be:

• no change
• smaller
• larger
• none of the above

The metric unit for velocity is ________.

• m
• m/s
• m/s²
• s

The metric unit for acceleration is ______.

• m
• m/s
• m/s²
• s

Acceleration is the rate at which _____ changes with time.

• position
• distance
• velocity
• none of the above

The slope of a velocity vs time graph is:

• position
• speed
• acceleration
• time
