F

Forces can be represented by arrows drawn to scale.

A student uses a scale of 1.0 cm to represent 5.0 N.

a.

An arrow is 4.0 cm long and points vertically downwards.

Give the size and the direction of the force that the arrow represents.

[2]
b.

Calculate the length of the arrow that represents a force of 32 N.

[2]
c.

The student draws an arrow 1.5 cm long pointing east to represent force X.

The student draws another arrow 1.5 cm long pointing west to represent force Y.

Another student says that force X and force Y are the same force.

Explain why the other student is wrong.
