Speed, Velocity & Acceleration

Front

What is the definition of velocity?

Back

Velocity is defined as speed in a given direction.

Front

How is speed calculated?

Back

Speed is calculated by dividing distance by time (Speed = Distance / Time).

Front

What does magnitude refer to in physics?

Back

Magnitude refers to the size or strength of a force.

Front

What is a force?

Back

A force is a push or a pull on an object.

Front

True or False: If you slow down on your bicycle, you are accelerating.

Back

True.

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 acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What units are commonly used to measure speed?

Back

Common units for speed include meters per second (m/s) and kilometers per hour (km/h).

Front

What is a vector quantity?

Back

A vector quantity is a quantity that has both magnitude and direction.
