Front

Velocity is a ___

Back

vector

Front

TRUE or FALSE: Speed is the absolute value of velocity.

Back

TRUE

Front

TRUE or FALSE: The path of falling objects looks like a line with a negative slope.

Back

FALSE

Front

Which Velocity-Time graph shows an object that's moving backward at a constant velocity?

Back

Graph G

Front

This symbol means 'Change in' or 'Final minus Initial'.

Back

Δ

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 positive slope on a distance-time graph indicate?

Back

An object is moving away from the starting point.

Front

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

Back

An object is moving back towards the starting point.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

What is the formula for calculating average speed?

Back

Average speed = Total distance / Total time.
