. What is the name of the force that causes unsupported objects to fall towards the Earth
gravity
air resistance
upthrust
Tick the name of the force that slows down an object falling through the air
gravity
air resistance
up thrust
Water resistance is the force that slows down objects moving through air.
true
false
Friction can cause heat to be produced.
true
false
The heavier the object, the stronger the force of gravity will be on it.
true
false
Label the arrows on the diagram to show which force is acting upwards on the diver and his parachute.
(a)
Label the arrows on the diagram to show which force is acting downwards on the diver and his parachute.
(a)
Which force is slowing the parachute down?
(a)
Which force is pulling the parachute down?
(a)
Rosie stands on some steps. she holds the piece of paper (see pic). Rosie let go of the paper. Luke times how long it takes for the paper to land flat on the surface. The force of gravity______________
pushes downwards
pulls downwards
pushes upwards
pulls upwards
Rosie folds the paper in half. She drops the paper again and Luke times it. They repeat the test, folding the paper in half each time. They measure the area each time they fold the paper. In the table (see pic attached) they record the time it takes for different pieces of paper to fall to the floor. How many times did they fold the paper that fell fastest.

Describe the link between the area of the paper and the time taken to land. which statement is true?
Smaller the area the quicker it fell. The larger the area the slower it fell.
Smaller the area the slower it fell. The larger the area the slower it fell.
Smaller the area the slower it fell. The larger the area the quicker it fell.
the children have some ideas to explain why the paper fell at different speeds. only ONE idea is correct
Carlton says that the folded paper is heavier than the unfolded paper.
Tasha says that there is more friction on the folded paper.
Rosie says that gravity is stronger on the folded paper
Luke says that there is less air resistance on the folded paper.
If there is water on the floor, is there more or less friction between the bottom of your shoe and the floor?
more
less
Investigating grip: Andy and jun have different ways of testing how well different shoes grip.
Andy's plan: 1:ask someone to run in the playground, 2:time how long it is before they fall over, 3: do the test again with different shoes.
Jun's plan: 1: put the shoe on the table and tie string to it, 2: add wight to the other end of the string and let it hang over, 3: see how much weight it takes to move each shoe. what unit of time will they use to measure?
seconds or minutes
minutes or millilitres
centimeter or meters

They decided to use Jun's plan to test some shoes (see picture). Jun predicts that shoe D will have the least grip. Explain why shoe D has the least amount of grip?
Less grip No marks, Smooth and No bumps.
less grip, no marks, rough and bumps
more grip, no marks, rough and bumps
Look at the table of results (see picture attached). Was Jun's prediction correct that shoe D will have the least grip?
yes
no
Explain your answer. Mark as many as you think are correct.
Less weight was needed meaning it was easier to move shoe D which means it had less friction.
More weight was needed for all others because they have less friction.
More weight was needed for all the others because they have more friction.
less weight was needed meaning it was harder to move shoe D which means it had less friction.
