Dive into the world of forces with this KS2 Science quiz! We'll explore air resistance, gravity, upthrust, and friction – the first of three quizzes on these amazing pushes and pulls.
Forces, like gravity and friction, are everywhere, making things change. Though we can't see them, we see their effects. Earth orbits the Sun because of gravity, and magnets move needles in compasses. Ever wondered how forces affect a boat on water or slow down a car? Test your knowledge in this fun Forces quiz!

You can find more about this topic by visiting BBC Bitesize - What is a force?
A force is always exerted either as a push or a pull
|
When labelling a diagram, you use arrows to show the direction of a force

The newton is named after the famous scientist Isaac Newton who you may have heard of
|
Another name for a forcemeter is a Newtonmeter

Electricity is a type of energy
|
Forces can speed things up and slow them down, push or pull them in a new direction, or squash and stretch them!

Gravity pulls the ball against the carpet. The ball rubs against the carpet, which is friction, and the air around the ball also rubs against it
|
Gravity pulls all objects (on the Earth's surface or in its atmosphere) down towards the centre of the Earth - the Earth's gravity even keeps the Moon in orbit because it pulls the Moon towards its centre (otherwise the Moon would travel in a straight line out into space)

The force of gravity acting on mass (the amount of matter in an object) is called weight - which is, of course, what makes an object feel heavy
|
Although weight is often given in kilograms and grams, this measurement really refers to mass. Weight is dependent on gravity and can change if the force of gravity is different (you wouldn't weigh the same on the Moon as you do on Earth, because the Moon has less gravity)
