Speed, Velocity and 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 of an object. It can be positive (speeding up) or negative (slowing down).

Front

How is Speed calculated?

Back

Speed = Distance / Time.

Front

How is Velocity calculated?

Back

Velocity = Displacement / Time.

Front

How is Acceleration calculated?

Back

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

Front

What is the difference between Speed and Velocity?

Back

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

Front

What does a positive acceleration indicate?

Back

A positive acceleration indicates that an object is speeding up.

Front

What does a negative acceleration indicate?

Back

A negative acceleration (deceleration) indicates that an object is slowing down.

Front

Can an object have a constant speed but changing velocity?

Back

Yes, if an object is moving in a circular path at a constant speed, its velocity is changing due to the change in direction.
