| Name a good thing that friction does | It helps to slow things down and it helps to grip objects, a common example is the bike. |
| Name a bad point on friction | It limits the top speed and wastes energy |
| What is air and water resistance ? | Resistance is the force that pushes objects backwards and air and water resistance is when this procedure is carried out in these conditions. |
| What can objects do to face less resistance? | They can be streamlined to avoid resistance. |
| What five things can forces do? | 1.Speed things up or start moving 2.Slow things down or stop moving 3.Change direction 4.Turn 5.Change shape |
| Do forces need to touch to interact? | No, forces like magnets and static electricity are good examples of this |
| What are forces measured in? | Newtons |
| What do balanced forces produce? | No change in movement |
| What do unbalanced forces do? | Change the speed or direction of moving objects |
