1. Bellwork You’re walking at constant speed, but still accelerating. What is the shape of your path?

2. Forces

3. Fundamental Forces Force of Gravity Electromagnetic force Strong Nuclear force Weak Nuclear force

4. Gravity Force that we experience everyday. The force that pulls objects toward one another On Earth-it pulls objects back to the ground

5. Balanced Forces Do Not cause a change in motion. They are equal in size and opposite in direction. Forces are equal and cancel each other out.

7. Unbalanced forces Causes a change in motion They are not equal and opposite The combined force is equal to the difference between the two forces and is exerted in the direction of the larger force.

9. Force is measured in Newton’s Brain Pop

10. Write down two things that stood out to you from the video.

11. Friction The amount of resistance between objects. Static Friction-the resistance of objects to move that are at rest Kinetic friction-force that opposes the movement of two surfaces that oar moving. Sliding Rolling
