Which scenario shows the release of chemical energy?
The diagram shows a hydroelectric power plant that uses moving water to power a toaster.
Which two sources of kinetic energy does the diagram show?
What can influence the electric potential energy of a system?
A camper uses a campfire to melt a marshmallow. Which form of energy produced by the burning wood in the campfire melts the camper's marshmallow?
Students perform a lab in which they place baking soda in a balloon and vinegar in a bottle. They place the balloon on the top of the bottle and lift the balloon releasing the baking soda into the vinegar. They balloon immediately inflates. What are the sources of chemical potential energy in this lab?
A student performs an activity to study kinetic energy. The student throws balls of different masses with a velocity of 2 m/s and records the kinetic energy, as shown.
What is the relationship between the ball and the kinetic energy of the ball?
The table shows the mass, velocity, and kinetic energy of two objects.
Based on the data, how does mass relate to kinetic energy?
A child is pushing a cart across the floor, and the cart moves at a certain speed. When he pushes the cart with a greater force, the cart begins to move faster. Which type of energy increases when the child applies a greater force?
What affects the amount of kinetic energy of an object?
If an object's speed is doubled, what happens to its kinetic energy?
