Speed, Velocity, and Acceleration
Average speed equals:
- Distance/ Time
- Time/ Distance
- Distance + Time
Velocity is the:
- measure of time and distance
- measure of space and time
- measure of speed that is constant
- measure of speed in a certain direction
What information is required in order to measure speed?
- time and distance
- velocity and time
- distance and velocity
- momentum and time
This describes how far an object moves during a certain amount of time.
- average speed
Acceleration refers to
- increasing speed
- decreasing speed
- changing direction
- all of the above
An object will not change its velocity if a force acts upon it.
What does a car's speedometer measure?
The slope of a distance-time graph correlates to:
Calculate the average speed of a bicycle that travels 100m in 20 s.
If you speed up from rest to 12 m/s in 3 seconds, what is your acceleration?
- 4 m/s/s
- 36 m
- 36 m/s
