When you kick a soccer ball what force are you using
Push
If group A pulls towards to the Left with a force of 340N and group B pulls towards the right with a force of 340N explain the motion the people will experience.
They will not move as the forces are balanced.
Explain why we have 40km/ h school zones.
Any of these:
The stopping distance is shortened when someone is travelling at a lower speed so they can avoid hazards.
At a lower speed, the cars have less inertia and if there was a collision would impact the object less.
Going at a slower speed allows for your reaction time better before a collision.
What causes you to stay seated while in your chair?

When something is moving, it is in
Motion

Inertia
Susan will use a _______ to make something move

Is gravity a big force or a small force?
A small force
Explain why it's easy to lift someone in the water compared to on land using the terms mass and weight.
The mass of the person hasn't changed.
What has changed is their force as the water is reducing the weight force that is pulling them down.
That friend of yours who is so heavy on the land seems a lot lighter in the water because of buoyancy. It's easier to lift your friend in the water, because the water itself pushes against your friend, helping you lift him much easier than you could ever do on land!
