Speed Velocity and Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s) or kilometers per hour (km/h).

Front

What is the formula to calculate speed?

Back

Speed = distance/time

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is the formula to calculate velocity?

Back

Velocity = displacement/time

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time.

Front

What is the formula to calculate acceleration?

Back

Acceleration = (final velocity - initial velocity) / time

Front

What are the units of acceleration?

Back

The units of acceleration are meters per second squared (m/s²).

Front

What does a positive acceleration indicate?

Back

A positive acceleration indicates that an object is speeding up.

Front

What does a negative acceleration indicate?

Back

A negative acceleration (deceleration) indicates that an object is slowing down.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).
