Forces
- Intro
- Forces are
pushes and
pulls between
two objects
- Forces are measured
in Newtons (N)
- Types of Forces
- magnetism
- air and
water
resistance
- friction
- gravity
- upthrust
- thrust
- static
electricty
- Non Contact and
Contact
- A contact force is any force that
requires touching to occur between
objects
- eg. friction, upthrust
- A non-contact force is a force
which acts on an object without
coming physically in contact with
- eg. magnetism, static
electricty, gravity
- Mass and Weight
- Weight is a force and is
caused by pull of gravity
acting on a mass
- Mass is the amount of matter
in an object and is measured
in kilograms
- Unbalanced and
balanced forces
- The forces are unbalanced which can
lead to change in speed or direction
