- 1What is the formula triangle for speed?The triangle is set up with distance (D)
over speed (S) and time (T) - 2What is friction?Friction is a force that acts opposing towards other forces.
- 3Name a good thing that friction doesIt helps to slow things down and it helps to grip objects, a common example is the bike.
- 4Name a bad point on frictionIt limits the top speed and wastes energy
- 5What 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.
- 6What can objects do to face less resistance?They can be streamlined to avoid resistance.
- 7What 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 - 8Do forces need to touch to interact?No, forces like magnets and static electricity are good examples of this
- 9What are forces measured in?Newtons
- 10What do balanced forces produce?No change in movement
- 11What do unbalanced forces do?Change the speed or direction of moving objects
