Forces 03
Gravity, air resistance and friction are the forces acting on a child going down a slide.

Forces 03

Explore the exciting world of push and pull forces in KS2 Science with this quiz – the last of three quizzes on these fascinating forces, including magnetism and water resistance!

Friction slows things, gravity pulls to Earth, magnetism attracts metals, and air or water resistance drags on moving stuff. Now, test if you can identify forces in different situations. Is it magnetism, gravity, or maybe upthrust? Challenge yourself with this final quiz on forces and see if you can spot these amazing push and pull powers at work!

Quizzes: The Path to Smart and Happy Kids
1 .
Which forces are acting on a child who is going down a slide?
Gravity, air resistance and friction
Gravity, air resistance and water resistance
Gravity, magnetism and friction
Gravity only
Gravity pulls the child downwards, friction from the slide and air resistance both slow the child down
2 .
A toy plastic boat floating in a bucket of water is experiencing which forces?
Gravity and upthrust
Magnetism and gravity
Magnetism and upthrust
Water resistance and magnetism
Upthrust is the force that prevents the boat from sinking. All objects on Earth experience gravity all of the time
3 .
Imagine someone cycling up a steep hill. Which forces are being experienced by the cyclist's shoes?
Gravity, magnetism and a push
Gravity, air resistance, a push, a pull and friction
Air resistance, a push and magnetism
Gravity and water resistance
Gravity is always being exerted on objects, air resistance results from moving through the air, and friction results from the shoe's 'grip' on the pedals. The cyclist pushes down on the pedals (through the shoes) and pulls up after each push
4 .
A row boat being rowed across a lake is experiencing which forces?
Gravity and upthrust
Gravity and water resistance
Gravity, upthrust and water resistance
Gravity, upthrust, water resistance, air resistance and a push
The push comes from the rowing of the oars pushing the boat forwards through the water
5 .
What type of force is air resistance?
A pull
Friction
Gravity
Magnetism
Air resistance and water resistance are both types of friction - air resistance is the friction an object experiences when moving through air and water resistance is the friction an object experiences when moving through water
6 .
What type of force is water resistance?
Gravity
Upthrust
Friction
Water resistance is not a force
Water resistance slows things down, just like air resistance
7 .
What forces are acting on a parachute as it falls through the air?
Upthrust and air resistance
Friction and magnetism
Gravity and air resistance
Magnetism and water resistance
Gravity pulls the parachute down and air resistance slows its fall
8 .
Catapults are designed to provide a 'push' which will be stronger than the force of gravity - the object which is being catapulted should be aerodynamic to minimise which force?
Air resistance
Upthrust
Magnetism
All of the above
Aerodynamic objects have less friction with the air and so are slowed less by air resistance
9 .
Which forces do the tyres on a moving bicycle experience?
Gravity and a push
Gravity, upthrust, air resistance and magnetism
Gravity, water resistance and friction
Gravity, friction, upthrust, air resistance and a push
Although it can be hard to imagine, the road is exerting upthrust on the bike's tyres - this is the force that prevents the bike from sinking through the road!
10 .
A child at the top of a slide is experiencing balanced forces. What force is needed to start the child sliding?
Upthrust
A push
Gravity alone
Friction
At the top of the slide gravity is countered by upthrust
