Forces

Weight is a force measured in...

• Kilograms

• Newtons

• Grams

Which statments are true about GRAVITY?

• Objects with a large mass are difficult to lift

• It acts towards the centre of the Earth

• It doesn't act on a flying aeroplane

• It makes the Moon orbits the Earth

Which of these is not a force?

• Weight

• Upthrust

• Mass

Where is your mass greater?

• On the Moon

• On Earth

• It's the same on the Moon as on Earth

Choose the odd one out about GRAVITY:

• Newtons

• Towards the centre of the Earth

• Pull force

• Archimedes

Choose the odd one out about UPTHRUST:

• Contact force

• Opposite to gravity

• Applied by water and air

• Non-contact force

Choose the odd one out:

• Push and pull force

• Attract and repel

• Magnetic field

• Contact force

Pikachu's mass is 6 kg. His weight on Earth is 60N.

What's his weight on the Moon?

• 9,6 N

  (because 6x1,6=9,6)

• 6 N

  (because 60:10=6)

What happens when two forces are equal and opposite?

• The forces are balanced

• The object doesn't move

• The forces are unbalanced

• The object moves

What happens when a force in one direction is bigger than a force in the opposite direction?

• The forces are balanced

• The object doesn't move

• The forces are unbalanced

• The object moves
