Force & Motion

Front

What is the amount of separation between 2 points?

Back

Distance

Front

What are forces that are equal in size acting on an object in different directions and do not cause a change in motion?

Back

Balanced forces

Front

What does a motion graph that shows no change in position over time represent?

Back

Body at rest

Front

If a man and a ball travel 90 m in 9 seconds, what is their average speed?

Back

10 m/s

Front

Which scenario best illustrates Newton's first law of motion?

Back

A ball rolling on a flat surface eventually stops due to friction.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

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 is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause a change in the motion of an object.
