Velocity, Position vs Time, & Acceleration

Front

What is velocity?

Back

Velocity is a description of the speed and direction of an object's motion.

Front

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

Back

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

Front

How do you calculate slope on a graph?

Back

Slope is calculated as rise over run.

Front

What is acceleration?

Back

Acceleration is the rate at which an object's velocity changes over time.

Front

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

Back

It means the object is moving at the same speed and in the same direction.

Front

What happens to the velocity of a car going around a corner?

Back

The car accelerates because it is changing 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 does a negative slope on a position vs time graph indicate?

Back

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

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has magnitude only, such as speed.

Front

What is a vector quantity?

Back

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