Speed, Velocity, & Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, measured in meters per second (m/s).

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is velocity?

Back

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

Front

How is velocity different from speed?

Back

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

Front

What is acceleration?

Back

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

Front

What is the formula for calculating acceleration?

Back

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

Front

What units are used to measure acceleration?

Back

Acceleration is measured in meters per second squared (m/s²).

Front

If a car travels 100 meters in 5 seconds, what is its speed?

Back

Speed = 100 m / 5 s = 20 m/s.

Front

What factors does speed depend on?

Back

Speed depends on distance and time.

Front

If a runner moves 200 meters north in 10 seconds, what is their velocity?

Back

Velocity = 200 m north / 10 s = 20 m/s north.
