What is speed?
Speed is a scalar quantity that refers to how fast an object is moving
What is the equation for speed?
Speed = distance/ time
What is velocity?
The velocity of an object is its speed in a particular direction. Velocity is a vector quantity because it has both a magnitude and an associated direction. To calculate velocity displacement is used in calculations rather than distance.
What is acceleration?
The acceleration of an object is its change of velocity per second. The unit for acceleration is m/s^2
What is the equation for acceleration?
Acceleration = change in velocity/time taken for the change
In a velocity time graph which direction is the line if the object is moving at constant velocity?
The line is horizontal
In a velocity time graph which direction is the line if the object has constant acceleration?
The line is diagonal
What is deceleration?
A car decelerates when the driver brakes. The term deceleration is used for any situation where an object slows down.
