Speed and Acceleration

Front

What is velocity?

Back

Velocity is a vector quantity that refers to the rate at which an object changes its position. It includes both speed and direction.

Front

What two measurements are necessary for calculating speed?

Back

Distance and time.

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be calculated as the final speed minus the initial speed, divided by the time taken.

Front

How is acceleration defined?

Back

Acceleration is defined as the change in velocity of an object divided by the time interval over which the change occurs.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What does a positive acceleration indicate?

Back

A positive acceleration indicates that an object is speeding up.
