Resistance
True or False: Resistance only applies to the air.
False. It can also occur in water.
True or False: Gravity only impacts heavy objects.
False. Gravity acts on all objects.
True or False: aluminium is magnetic
False. Examples: tinfoil and pop can tabs
Define force
A push or pull
Provide an example of resistance
Paper falling, feather falling, bike moving through grass, swimming.
Provide an example of gravity
Object falling off a desk...
Provide an example of a magnetic object/item.
Paper clips, bolts, nickels and dimes.
True or False: forces are invisible.
True! We can see the impact of the force but not the force itself.
What is the word that describes two objects rubbing together.
Friction.
What direction does gravity pull?
Gravity pulls objects down (to the centre of the Earth).
True or False: Iron is magnetic
True!
True or False: Only one force can be in action at a time.
False. Forces can work at the same time (think a feather falling)
Why do engineers try to make cars smooth and rounded instead of box-shaped?
Smooth shapes reduce the air pushing against the car, so it can move more easily.
Is there more or less gravity on the moon?
Less.
Explain how distance impacts magnetism
The further you move the magnetic items apart, the weaker the force.
How are the forces of gravity and resistance similar?
They are all forces — they can push, pull, slow down, or change movement.
They affect how objects move or stop moving.
We can see their effects, even if we can’t always see the force itself.
Why would adding wheels to a heavy box make it easier to move across the floor?
Because wheels reduce the rubbing between surfaces, so there is less resistance.
Is there more or less gravity on Saturn?
more.
Explain the forces of attraction and repulsion in magnetism.
Two south poles and two north poles = repel, North + south pole = attract.
What does "non contact" force mean?
a force that can push or pull something without touching it.
