| Question | Answer |
|---|---|
| A force that tries to slow things down that are moving through air. It is a type of friction. | air resistance |
| A force that needs to touch an object before it can affect it (e.g. friction). | contact force |
| Air resistance and water resistance are both sometimes called | drag |
| A push or a pull. | force |
| Piece of equipment containing a spring, used to measure forces. | force meter |
| A force that tries to slow things down when two things rub against each other. | friction |
| The force of attraction between any two objects. | gravity |
| A force that attracts objects made out of iron. | magnetism |
| The unit of force. | newton (N) |
| Another name for a force meter. | newton meter |
| A force that can affect something from a distance (e.g. gravity). | non-contact force |
| How fast something is moving. | speed |
| A force which attracts things with extra electrical charges on them. | static electricity |
| A force that pushes things up. | upthrust |
| A force that tries to slow things down that are moving through water. It is a type of friction. | water resistance |
| The amount of mass that 1 cm3 of a substance has. Measured in g/cm3. | density |
| The volume of water pushed out of the way by an object. | displacement |
| A force that pushes thing up. | upthrust |
| When two forces are the same strength, but working in opposite directions. | balanced forces |
| Any substance that will return to its original shape and size after it has been stretched or squashed. | elastic |
| A unit for measuring mass | gram |
| The amount of matter that something is made of. Measured in grams (g) | mass |
| The unit of force | newton |
| Not moving. | stationary |
| When two forces working in opposite directions are not the same strength. | unbalanced forces |
| The amount of force with which gravity pulls something towards the Earth. It is measured in newtons (N). | weight |
| A substance (normally a liquid) used to reduce friction. | lubricant |
| The distance a car travels while the brakes are trying to stop it. | braking distance |
| A graph that shows how far and how fast something travels during a journey. | distance/time graph |
| The distance a car travels while the driver is deciding to press the brake pedal. | thinking distance |
