Speed, Velocity, Acceleration

Front

What is the law of inertia?

Back

An object in motion stays in motion, and an object at rest stays at rest unless acted on by an unbalanced force.

Front

What is velocity?

Back

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

Front

What two factors does velocity depend on?

Back

Speed and direction.

Front

What is speed?

Back

Speed is the distance traveled per unit of time.

Front

What two factors does speed depend on?

Back

Distance and time.

Front

How does increasing force affect the speed of an object?

Back

Increasing the force on an object will increase the speed of the object.

Front

What is acceleration?

Back

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

Front

What is the formula for acceleration?

Back

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

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).

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has only magnitude, such as speed.
