Speed, Velocity & Acceleration

Front

What is Speed?

Back

Speed is the distance traveled per unit of time. It is a scalar quantity, meaning it has only magnitude and no direction.

Front

What is Velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is Acceleration?

Back

Acceleration is the rate of change of velocity per unit of time. It can be positive (speeding up) or negative (slowing down).

Front

What is the formula for Speed?

Back

Speed = Distance / Time.

Front

What is the formula for Velocity?

Back

Velocity = Displacement / Time.

Front

What is the formula for Acceleration?

Back

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

Front

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

Back

Speed = 100 meters / 5 seconds = 20 meters per second.

Front

If a runner moves 10 meters North in 2 seconds, what is their velocity?

Back

Velocity = 10 meters North / 2 seconds = 5 meters per second North.

Front

What happens to the acceleration of an object if it is moving at a constant speed?

Back

If an object is moving at a constant speed, its acceleration is zero.

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).
