acceleration
|
change in velocity per unit of time
|
|
|
What is the acceleration due to gravity?
|
9.8 m/s/s (meters per second per second).
The velocity increases by 9.8 m/s every second something falls. |
|
|
What is the difference between speed and velocity?
|
Speed is a general measure of how fast something is moving (distance per unit time). Velocity is a specific measure which must include the direction of movement.
|
|
|
How do you find the average velocity of something moving at constant acceleration?
|
Add the initial and final velocities and divide by 2.
|
|
|
What is constant acceleration?
|
Acceleration at a constant rate - the acceleration doesn't change.
