When does a ball thrown into the air have its greatest kinetic energy?
The ball has its greatest kinetic energy at the moment it is released or thrown, just before it reaches its peak height. This is because it has the highest velocity at this point, which is a key factor in determining an object's kinetic energy.
Which has more kinetic energy a ball dropped from a height of 2m or a same ball dropped at 4m which has more kinetic energy just before it hits the ground?
The ball dropped from 4m height has more kinetic energy just before it hits the ground because it has a higher velocity due to falling from a greater height. Kinetic energy is directly proportional to both mass and the square of velocity, so the ball dropped from 4m height will have more kinetic energy than the one dropped from 2m height.
A bowling ball striking the pins is kinetic or potential energy?
When a bowling ball strikes the pins, it is kinetic energy because it is in motion. Potential energy refers to stored energy that has the potential to do work, such as when the ball is held at the top of a ramp before being released.
How would you put the potential energy definition for kids?
Potential energy is like storing energy in a hidden place. Just like a ball placed at the top of a slide has potential energy because it can roll down and turn into kinetic energy when released.
A ball is thrown vertically upward what is the acceleration of the ball just before it hits the ground?
The acceleration of the ball just before it hits the ground is equal to the acceleration due to gravity, which is approximately 9.81 m/s^2 downward.

Can the Newton's Cradle possess potential energy?
Sure, when the ball is in the highest position, it has a maximum amount of potential energy. When it is just about to hit the other balls, the potential energy has been converted to kinetic energy. When the other ball goes up again, the kinetic energy turns, once more, into potential energy.Sure, when the ball is in the highest position, it has a maximum amount of potential energy.

If you toss a ball in the air at what point does it have the most kinetic energy?
As soon as the ball has been released.In this case, the energy starts off purely kinetic; dependent on motion. Once the ball has reached it's highest point, it has converted to potential energy; dependent on height. It then resumes falling back to kinetic energy. This is best shown by a graph of energy over time where Potential energy is a parabola opened down (frown face) and Kinetic energy is a parabola opened up (smiley face).With this you can also note that Kinetic Energy + Potential Energy = mechanical energy. These two graphs added together should make a straight line for Mechanical energy (in simplistic demonstration).
How does a magnetic accelerator work?
Energy changes from ball to ball down the accelerator just as it does in Newton's cradle. It functions on the transfer of momentum.
If you throw a ball into the air where will it have the greatest gravitational potential energy?
The ball has the highest gravitational potential energy when it is at its highest point in the air, as that is when it has a velocity of zero and is up the highest.
Which device is used for converting potential energy into kinetic energy?
There is no "device" that is used to convert potential energy (PE) to kinetic energy (KE). PE is energy of position, for example, a bowling ball held over your head has the potential of breaking your foot if it were to fall. KE is energy of motion, for example, the energy the bowling ball has as it is falling toward your foot. The amount of PE the bowling ball had when it was motionless at some height above your head is approximately equal to the amount of KE the bowling ball has just before it lands on your foot.
How is the law of conservation of energy obeyed when a tennis ball gets warm when bouncing?
A moving tennis ball (or a moving object of any type) has kinetic energy, the enery of motion. Some of this energy gets converted into heat, when the ball bounces, and the ball therefore gets warm. The ball is moving less, but the kinetic energy has not disappeared, it has just changed into another form of energy.
A ball is thrown upward What can be said about the system?
Well, honey, when a ball is thrown upward, the system is experiencing an increase in potential energy and a decrease in kinetic energy. As the ball reaches its highest point, its potential energy is at its maximum and its kinetic energy is at its minimum. Once gravity takes over and brings that ball back down, the potential energy decreases while the kinetic energy increases. It's just physics doing its thing, darling.
