When an object applies a force on a second object, the second object applies the same force in the opposite direction.
What are 2 factors that affect Kinetic energy?
Mass and Velocity
If there is no net force on an object, what will happened to the object's motion?
The object will remain at rest or if it is in motion, it will continue to move at the same velocity (no acceleration)
Which NBA player holds the record for most points in a single basketball game?
Wilt Chamberlain
Is a balanced or unbalanced force acting on the 2nd object? Will the object accelerate?
Unbalanced Force. The Object will accelerate.

At what point on a roller coaster would a person have the greatest potential energy? At what point would they have the greatest kinetic energy? Explain
Greatest Potential Energy- at the top of the roller coaster
Greatest Kinetic Energy- at the bottom of the highest loop
Irene and Valerie are in a dogsled race. Using the equations for Newton’s second law, who would MOST LIKELY win if each dog pulls with a force of 50 N?
• Irene has 8 dogs and a sled with a total mass of 500 kg.
• Valerie has 7 dogs and a sled with a total mass of 700 kg.
Irene; A = .8 m/s^2
Name the 5 Oceans that exist on Earth.
Atlantic, Pacific, Indian, Southern, and Arctic.
An object is moving at 10 m/s. A net force of 0N is applied to the object. What will happen to the velocity of the object? Why?
The object's velocity will NOT change because a balanced force is applied to it.
