Energy, Forces, and Motion 8th Grade Review

Here is a video explaining balanced and unbalanced forces. Balanced vs Unbalanced Forces Click each box to sort it into the correct category Balanced Forces Net force = 0N Does not cause acceleration Object will stay at rest Object will stay at a constant speed All the forces are equal Unbalanced Forces Net force doesn't = 0N Causes acceleration Object will speed up, slow down, or change direction Object will accelerate All the forces are not equal What will happen to the cart? The cart will accelerate to the right with the force of 8 newtons. The cart will accelerate to the left with the force of 3 newtons. The cart will accelerate to the right with the force of 5 newtons. The cart will remain at rest. What will happen to the cart? The cart will accelerate to the right. The cart will move to the right at a constant speed. The cart will accelerate to left. The box was moving to the left, what will happen when these forces are applied? The box will speed up. The box will slow down and stop. The box will continue to move to the left at a constant speed. Label which is experiencing balanced forces and which are unbalanced forces. Use the terms: balanced and unbalanced Balanced Unbalanced Unbalanced What is the net force? 3 N to the right 17 N to the right 17 N to the left Potential vs Kinetic Energy Which are examples of potential energy? Which are examples of kinetic energy? Potential Energy Standing at the top of a diving board. Standing on the pitchers mound. Golf ball on a tee. Compressed Spring Loose rubber band. Kinetic Energy Diving off a diving board. Running around 1st base. Golf ball flying through the air. Released Spring Tight rubber band.
