machine

Question 3

ramp

Answer 3

A sloping surface. A ramp is a force multiplier: it needs less force to pull something up a ramp than it does to lift it directly.

Question 5

pulley

Answer 5

A simple machine consisting of a wheel that can turn on an axis with a rope running around it. Using more than one pulley with a rope allows a force to be multiplied.

Answer 6

pulley

Question 7

work

Answer 7

The energy transferred when a force moves an object. It is calculated using the size of the force and the distance moved by the force. The unit for work is the joule (J).

Question 8
