Front

What is a quantity that has magnitude and direction called?

Back

Vector quantity

Front

Which scenario does NOT demonstrate acceleration? A car using cruise control on a straight road, A bicycle stopping, A runner taking off from blocks on the track, A car taking a turn at a constant speed?

Back

A car using cruise control on a straight road

Front

What unit do we measure time in?

Back

s

Front

What would the d-t graph look like for an object travelling at a constant velocity?

Back

Straight line

Front

What is the definition of velocity?

Back

Velocity is the speed of an object in a given direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What does a curved line on a d-t graph indicate?

Back

A curved line indicates that the object is accelerating.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final velocity - Initial velocity) / Time taken.

Front

What does a horizontal line on a d-t graph represent?

Back

A horizontal line indicates that the object is at rest.
