What is Speed?

Back

Speed is the distance traveled per unit of time, typically measured in kilometers per hour (km/h) or miles per hour (mph). It 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, meaning it has both magnitude and direction.

Front

What is Acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is the difference between Speed and Velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has only magnitude and no direction, such as speed or distance.

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction, such as velocity or acceleration.

Front

How do you calculate Speed?

Back

Speed can be calculated using the formula: Speed = Distance / Time.

Front

How do you calculate Acceleration?

Back

Acceleration can be calculated using the formula: Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What happens to the velocity of an object when it accelerates?

Back

When an object accelerates, its velocity changes; it can either increase or decrease depending on the direction of the acceleration.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's velocity changes at a constant rate over time.
