Speed, Velocity, Acceleration

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be a change in speed or direction.

Front

What is speed?

Back

Speed is the distance traveled per unit of time, regardless of direction. It is a scalar quantity.

Front

What is velocity?

Back

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

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the unit of speed in the metric system?

Back

The unit of speed is meters per second (m/s).

Front

What happens to acceleration when an object slows down?

Back

When an object slows down, it experiences negative acceleration, also known as deceleration.

Front

How can 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 meters in 5 seconds, what is its speed?

Back

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

Front

What does it mean if an object has a constant velocity?

Back

It means the object is moving at a constant speed in a straight line without changing direction.
