1Set 3: Chapter 5.2 pgs. 115-118 What is a force? Objectives: Give examples of different kindsof forces.Determine the net force on an objectCompare balanced and unbalanced forces.
2What is a Force?A force is simply a push or a pull.
3When you’re really, really smart…… The Newton(N)They name a unit of measure after you!
4Examples of Different Types of Forces Gravitational ForceFriction
5Net Force: is the force that results from combining all the forces exerted on an object Forces in the Same Direction: You just add the forces together!Forces in the Opposite Direction:You subtract the larger force from the smaller force.
6Balanced Forces Balanced Forces Produce No Change in Motion. The Net Force is Zero.
7Unbalanced Forces Unbalanced Forces Produce a Change in Motion. The Net Force on the Object is Not Zero.
8Can You? 1. Tell me what a Force is? 2. Tell me what is the Unit of Measure of Force?3. Tell me what is the Net Force?Tell me what is the difference between Balanced and Unbalanced forces?
