Speed, Velocity, & Acceleration

Front

What is Speed?

Back

Speed is the distance traveled per unit of time. It is a scalar quantity and does not include direction.

Front

What is Velocity?

Back

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

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

How do you calculate Speed?

Back

Speed = Distance / Time.

Front

How do you calculate Velocity?

Back

Velocity = Displacement / Time.

Front

How do you calculate 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

If a car travels 100 km in 2 hours, what is its speed?

Back

Speed = 100 km / 2 hours = 50 km/h.

Front

If a train travels 300 km north in 3 hours, what is its velocity?

Back

Velocity = 300 km north / 3 hours = 100 km/h 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.
