Physical Science Force and Motion

Front

What is instantaneous speed?

Back

The exact speed of an object at a particular moment in time.

Front

What is the difference between speed and velocity?

Back

Velocity has direction, while speed does not.

Front

What type of quantity is displacement?

Back

Displacement is a vector quantity.

Front

What are the standard units for speed?

Back

Meters per second (m/s).

Front

Define speed.

Back

Speed is the distance traveled per unit of time.

Front

Define velocity.

Back

Velocity is the displacement per unit of time, including direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is a scalar quantity?

Back

A scalar quantity has only magnitude and no direction.

Front

What is a vector quantity?

Back

A vector quantity has both magnitude and direction.
