Speed Velocity and Acceleration

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 the speed and direction of the object's motion.

Front

What two factors does speed depend on?

Back

Speed depends on distance and time.

Front

What does a constant speed on a distance-time graph indicate?

Back

A constant speed on a distance-time graph indicates that the object is moving at a steady rate without acceleration.

Front

How is average speed calculated?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the formula for calculating acceleration?

Back

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

Front

What does a negative acceleration indicate?

Back

Negative acceleration, also known as deceleration, indicates that an object is slowing down.

Front

How can you determine if an object is accelerating?

Back

An object is accelerating if its velocity is changing, which can be observed through changes in speed or direction.

Front

What is the significance of direction in velocity?

Back

Direction is significant in velocity because it determines the vector nature of velocity, distinguishing it from speed.

Front

What is the unit of speed in the metric system?

Back

The unit of speed in the metric system is meters per second (m/s).
