Define ‘water resistance’
A contact force that arises when an object moves through water
Define ‘air resistance’
A contact force that arises when an object moves
through air
What is the effect of friction, air resistance and
water resistance on a moving object?
They slow down moving objects
Define ‘upthrust’
The force of a liquid pushing up against the weight of a solid
Define ‘magnetic force’
The force between two magnets
Define electrostatic force
The force acting between two charged objects.
Define tension
A force that extends/pulls apart an object
Define compression
A force that squashes/pushes together an object
define normal contact force
Puh force acting between two solid objects
Define driving force
The force that is pushing or pulling something.
define gravity
A non-contact force that pulls objects towards the
ground
What is mass?
The amount of matter an object is made up of.
What is weight?
the force of the earth on an object
What two factors does the weight of an object
depend on?
What two factors does the weight of an object
depend on?
How would you calculate the weight on an
object?
Weight = mass x strength of gravity
