How can forces affect objects?
- slow them down - speed them - stop them - start them -change their direction -change their shape Balanced Forces - when all the forces acting on the object balance each other - balanced forces do not cause a change in motion |
Unbalanced Forces
- when all the forces acting on the object are not equal - unbalanced forces causes change in motion Friction - force that resist motion between touching surfaces - acts in the opposite direction of the objects motion -produces heat |
