What best describes the changes in energy as a child goes down a slide?
The kinetic energy of the ball the instant it hits the floor is_______J. Which best describes the changes in energy as a child goes down a slide? The ball slows down as it rolls because friction exerts an unbalanced force.
At which position does the ball have the most potential energy?
top
The ball at the top of the swing is briefly motionless. It has the greatest potential energy, because it is highest above the surface. At every point in the swing, the system of the ball on the pendulum string has the same total amount of energy.
Which type of energy is being created when the girl goes down the slide?
As you go down the slide, the potential energy is converted to kinetic energy.
Which best describes the energy change that occurs when someone pushes a large rock down a hill?
Which best describes the energy change that occurs when someone pushes a large rock down a hill? Mechanical energy released when fuel is burned is converted into heat energy. Electricity generated when fuel is burned is converted into mechanical energy.
How does energy change when you go down a slide?
As you go down the slide, the potential energy is converted to kinetic energy. And the difference in your potential energy and kinetic energy is lost in the form of thermal energy due to friction.
Which type of energy commonly changes back and forth between kinetic and potential energy?
Mechanical energy
Mechanical energy commonly changes back and forth between kinetic and potential energy.
What happens in terms of energy when a moving car?
The moving car transfers kinetic energy to the parked car. Kinetic energy in the moving car disappears.
What type of energy is throwing a ball up?
kinetic energy
A thrown baseball has mechanical energy as a result of both its motion (kinetic energy) and its position above the ground (gravitational potential energy). Any object that has mechanical energy can do work on another object.
What energy does a ball have when it hits the ground?
As the ball falls towards the ground, its potential energy is transformed into kinetic energy, which will continue increasing as it gains momentum, until it finally collides with a surface.
