Presentation on theme: "Unbalanced Forces and Motion"— Presentation transcript:
1Unbalanced Forces and Motion What happens when multiple forces act on the same object?
2Net ForceNet Force is the difference of two or more forces acting upon an object.1000 N2000 NForce from paddlingCurrent from river
3Unbalanced ForceUnbalanced Forces happen when two unequal forces act on each other.Unbalanced forces set objects in motion.100 NForce of GravityNet Force 500 N up.600 NForce from kickers leg.
4Balanced ForceBalanced Forces are two equal forces that cancel each other out.Balanced forces cause a net force of zero.Net Force Zero happens when two equal forces cancel each other out.The force of gravity pulls the vase towards the ground.30 NNet Force Zero30 NThe force of friction from the table pushes up againstthe vase canceling out the force of gravity.
