Forces
| Force | a push or pull |
| Describe force: | By its strength and by the direction in which it acts |
| SI unit used to measure strength | newton |
| How can direction and strength of force be represented? | By an arrow (head tells direction) (length indicates strength) |
| Net force | the overall force on an object when all the individual forces acting on it are added together |
| What does net force determine? | whether an object moves and which direction it moves |
| How to find the net force when two forces act in the same direction? | add the strengths of the individual forces together |
| When two forces act in the same direction what does it do to the net force? | Produces a greater force |
| How do you find the net force when two forces act in opposite directions? | subtract the strengths |
| When two forces act in opposite directions what does it do to the net force? | produces a net force in the direction of the larger force |
| If the net force is zero will the objects motion change | no because the forces acting on the object are balanced |
| Unbalanced force | forces that produce a non zero net force(which changes an objects motion) |
| Balanced force | equal forces acting on an object in opposite directions |
| How do balanced forces acting on each other affect it's motion? | balanced forces cancel and do not change the objects motion |
