Distance / Time
1 of 10
What is Relative motion?
Two objects moving towards or away from each other
2 of 10
Forces are not always pushes or pulls. True or False????
False they are nearly always pushes and pulls (Always)
3 of 10
Name the five things forces can make an object do...
Speed up/start moving, Slow down/stop moving, Change direction, Turn and cange shape.
4 of 10
What is friction?
Friction is a force that acts in the opposite direction to movement.
5 of 10
Name something that friction allows....
Allows things to stop and start, allows more grip.
6 of 10
Friction is a wasted energy. True or false??
True. For example, friction between moving parts of the bike warms up the gears and bearings- therefore a waste of energy.
7 of 10
What does Waer and air resistance do?
They push against objects therefore slowing them down.
8 of 10
What can be done to help things be less effected by air resistance and water resistance?
Being more streamline. This means that they can slip through the air or water without much resistance.
9 of 10
Air resistance pushes things like a parachute upwards so they do not just fall. Is this statement true?
Yes , Weight of the person pushes down on the person but once the parachute is activated, air resistance pushes upwards on the parachute and slows it down.
