Speed, Velocity, Acceleration

Front

What is the definition of 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 definition of velocity?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, typically measured in meters per second squared (m/s²).

Front

How does increasing force affect speed?

Back

Increasing the force on an object will increase its speed.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that does not involve direction, while velocity is a vector quantity that includes direction.

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has magnitude only and no direction, such as speed.

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction, such as velocity.

Front

Give an example of velocity.

Back

A car driving 55 miles per hour south is an example of velocity.

Front

What happens to an object's speed if it experiences negative acceleration?

Back

If an object experiences negative acceleration, its speed decreases.

Front

What is the formula for calculating acceleration?

Back

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