Speed and Velocity

Front

What is speed?

Back

Speed is a scalar quantity that refers to how fast an object is moving, defined as the distance traveled per unit of time.

Front

What is velocity?

Back

Velocity is a vector quantity that refers to the rate at which an object changes its position, including both speed and direction.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What does a positive slope on a position-time graph indicate?

Back

A positive slope indicates that the object is moving away from the starting point.

Front

What does a negative slope on a position-time graph indicate?

Back

A negative slope indicates that the object is moving back towards the starting point.

Front

What does a slope of zero on a position-time graph indicate?

Back

A slope of zero indicates that the object is at rest.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, indicating how quickly an object is speeding up or slowing down.

Front

How do you calculate acceleration?

Back

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

Front

What does the slope of a velocity-time graph represent?

Back

The slope of a velocity-time graph represents acceleration.

Front

What is the difference between average speed and instantaneous speed?

Back

Average speed is the total distance traveled divided by the total time taken, while instantaneous speed is the speed of an object at a specific moment in time.
