What is kinetic energy?
This is where an object is located relative to another object.
What is relative position?

In a game of tug-of-war, one team pulls harder and moves the rope closer to their side, while the other team pulls weaker and moves the rope away from them. This shows the impact of ____ when moving an object.
What is force?
A push or a pull on an object that changes its motion.
What is force?
A snowball is rolling down a hill. Evaluate at what point the ball will have equal potential and kinetic energy.
1. When the snowball is at the top of the hill
2. When the snowball is halfway down the hill
3. When the snowball is at the bottom of the hill

What is the golf ball?
A measure of how much matter is present in a substance.
What is mass?
This states that matter can never be created nor destroyed.
What is the Law of Conservation of Energy?
Which of the following would be an example of potential energy?
1. A battery not in anything
2. A battery powering a lightbulb
3. A book falling off a shelf
4. A book sliding down a ramp
What is option 1: a battery not in anything?
Kinetic energy is energy related to the _______of objects or particles.
What is motion?
Students conduct an experiment where they send golf balls down a ramp. Ball 1 is dropped on the ramp, Ball 2 is gently pushed down the ramp, and Ball 3 is thrown down the ramp. Ball 3 makes it down the ramp the fastest. State the question the students are investigating.
Can force have an affect on speed?
The rate of change of position (or distance traveled) with respect to time.
What is speed?
A diver standing on top of a diving platform that is 20 meters above the pool dives off the platform. Describe the transfer of energy that occurs during the fall.
How does the diver start with potential energy and end with kinetic energy?
Madison pushed a ball down a hill. The ball has ________ energy when it is not moving. Madison exerts ________ on the ball to initially move it. The ball’s energy has now become _______ energy because it is now moving.
Potential, force, kinetic

What two things can increase that can lead to kinetic energy increasing?
1/2 credit for each answer.
What are speed and mass?
Students conduct an experiment using a toy car with a mass of 20g, a toy car with a mass of 30g, and a toy car with a mass of 40g. The students want to see how far a car can travel from the top of a ramp. Evaluate the information and determine the question they are trying to test with this experiment.
Does the mass of a car affect its kinetic energy/
The change in an object’s position with respect to time and in comparison with the position of other objects used as reference points.
What is motion?
A car traveling 30 mph requires about 15 meters to come to a complete stop. A car traveling 60 mph requires about 55 meters to stop. Evaluate a conclusion about the relationship between speed and stopping a car.
Why do cars with more kinetic energy require more energy to stop?
