Potential and Kinetic Energy BackgroundPotential energy is stored energy. Often, the energy is stored due to an object’s position, such as its position above the ground. The amount of potential energy depends on the height of the object above the ground. The amount of potential energy also depends on the mass of the object.Kinetic energy is energy of motion. Objects in motion have kinetic energy. Kinetic energy depends on how fast the object is moving. Kinetic energy also depends on the mass of the object.When an object is up high, it has potential energy. If it falls or rolls downward, its potential energy is converted to kinetic energy as it falls or rolls downward. As its kinetic energy increases, its speed increases.Imagine a ball rolls down a hill. Its potential energy decreases, and its kinetic energy increases.Now imagine that ball hits a plastic cup at the bottom of the hill. The ball’s kinetic energy can be used to move that cup. The more kinetic energy the ball has, the more it can move the cup it hits at the bottom of the hill.Question 11.

Changing the height of an object above the ground will affect its potential energy. Increasing the object's height above the ground will increase its potential energy. This means that the object will have more stored energy. For example, if you lift a book off the ground and place it on a higher shelf, its potential energy will increase because it is now higher above the ground.
Conversely, decreasing the object's height above the ground will decrease its potential energy. This means that the object will have less stored energy. For example, if you lower the book from the higher shelf to a lower shelf, its potential energy will decrease because it is now closer to the ground.
Changing the mass of an object will also affect its potential energy. Increasing the object's mass will increase its potential energy. This means that the object will have more stored energy. For example, if you add more books to a stack, the potential energy of the stack will increase because there is now more mass.
On the other hand, decreasing the object's mass will decrease its potential energy. This means that the object will have less stored energy. For example, if you remove some books from the stack, the potential energy of the stack will decrease because there is now less mass.
In summary:
- Increasing the height or mass of an object will increase its potential energy.
- Decreasing the height or mass of an object will decrease its potential energy. WHAT WOULD THE FOUR CHOICES GO UNDER
increasing the object's height above the ground - This will increase the object's potential energy.
decreasing an object's height above the ground - This will decrease the object's potential energy.
increasing the object's mass - This will increase the object's potential energy.
decreasing the object's mass - This will decrease the object's potential energy.
are you sure i don't want to get this wrong
I apologize for any confusion. Here are the correct choices for how each property affects the potential energy of an object:
- Increasing the object's height above the ground: This will increase the object's potential energy.
- Decreasing the object's height above the ground: This will decrease the object's potential energy.
- Increasing the object's mass: This will increase the object's potential energy.
- Decreasing the object's mass: This will decrease the object's potential energy.

In this experiment, a ball rolls down a hill and hits a cup at the bottom. The hypothesis predicted if a ball with higher mass is used, that ball's kinetic energy at the bottom of the hill will beas compared to the kinetic energy of the ball with the lower mass. The kinetic energy of each ball was used to. The data showed that the ball with lower mass would move the cup at the bottom of the ramp a distance of. The data showed that the ball with a higher mass would move the cup at the bottom of the ramp a distance of. This means using a ball with an increased mass will result inin kinetic energy. The hypothesis was.Question 3
To determine the answer for question 3, I would need the specific data or values provided in the experiment. The question asks about the comparison of kinetic energy between a ball with higher mass and a ball with lower mass. Please provide the missing data or values, and I'll be happy to assist you further.

Instead of measuring energy directly, we measured and comparedin order to compare the energy levels of the two different balls at the bottom of the ramp.
In conclusion 1, the sentence should read:
"The hypothesis predicted if a ball with higher mass is used, that ball's kinetic energy at the bottom of the hill will be greater as compared to the kinetic energy of the ball with lower mass."
For question 3, it is stated that "Using a ball with a different mass changed the _____ of the ball at the bottom of the ramp, which is the energy of the ball due to its motion. Instead of measuring energy directly, we measured and compared _____ in order to compare the energy levels of the two different balls at the bottom of the ramp."
The missing words to fill in the blanks depend on the context of the experiment. Generally speaking, the first blank can be filled with "kinetic energy", as it refers to the energy of the ball due to its motion. The second blank can be filled with "distances moved by the cup" or "displacements", as it describes the measure used to indirectly compare the energy levels of the two balls.
Please provide the specific data or values for the distances moved by the cup by each ball, so that the blanks can be accurately filled.

Conclusion 1: In this experiment, a ball rolls down a hill and hits a cup at the bottom. The hypothesis predicted if a ball with higher mass is used, that ball's kinetic energy at the bottom of the hill will be greater as compared to the kinetic energy of the ball with the lower mass. The kinetic energy of each ball was used to determine the distances moved by the cup. The data showed that the ball with lower mass would move the cup at the bottom of the ramp a distance of 80 cm. The data showed that the ball with a higher mass would move the cup at the bottom of the ramp a distance of 279.5 cm. This means using a ball with an increased mass will result in higher kinetic energy. The hypothesis was supported.
(Note: Since the values provided for the distances of cup movement and the comparison of kinetic energy are specific to the experiment, they can be inserted into the appropriate places in the conclusion. Also, the support or rejection of the hypothesis will depend on whether the observed data aligns with the predicted outcome.)
