A ball is rolling along a straight and level path The ball is traveling at a constant speed of 2.0 ms The mass of the ball is 3.0 kg What is the kinetic energy of the ball?
Kinetic energy = 1/2 m V2 = 1/2 (3) (2)2 = 6 joules
What is a hypothesis for the gauss rifle?
If you use a bigger steel ball bearing than it will go farther than a smaller steel ball because of the amount of kinetic energy in each size ball.
How is kinetic energy in tennis?
Kinetic energy is energy in motion. So, there is kinetic energy when the ball is moving through the air. There is sciatic energy when the ball is resting on the racket! Hope this helps.
How do you Construct a model of an object that possess kinetic energy?
a ball at the top of a hill has potentail energy and when it is rolled is has kinetic.
A ball thrown by a boy from the roof top is what motion?
When the boy is holding the ball it has Gravitational Potential Energy (GPE).When he lets go the Gravitational Potential Energy is converted to Kinetic Energy.As the ball is falling it continues to gain Kinetic Energy, however, the friction from the air on the ball increases (Air Resistance).When the Kinetic Energy and Air Resistance become equal the ball is said to have to reached Terminal Velocity.Once the ball hits the ground the Kinetic Energy is transferred to the ground through heat (Friction) and also as sound.Remember energy cannot be created or destroyed, it is always transferred.

Throwing a ball is an example of Kinetic Energy.

Describe the conversions between potential and kinetic energy that occur when you shoot a basketball in a basket?
When the ball is positioned in your hands it has full potential energy. As you move and the ball is thrown at the basket, the potential energy is converted to kinetic energy, by the transfer of kinetic energy from your arms, to your hands, to the ball. When the ball hits the basket some of its kinetic energy was converted into potential energy and then back into kinetic energy as it hit the ground.
When you hold a ball above the ground does it have kinetic energy?
Yes and no. When the ball is at its highest point, it is storing potential energy. when it is moving back down, the potential energy turns into kinetic energy, and so forth. But when the ball is done bouncing, it doesn't technically "store" energy.
A girl throws a ball 15 m into the air the ball has the maximum potential energy at a height of?
The ball has the highest potential energy at its maximum height (15m in the air). At the beginning, the ball has only kinetic energy and no potential energy. But as the ball travels upward, kinetic energy is converted into potential energy. When the ball changes direction, there is no kinetic energy, as all of it is now potential energy. As the ball returns back down, potential energy is converted back into kinetic energy.
What makes a ball speed up when it is traveling down an inclined plane?
The conversion of Potential Energy (the energy something has as a result of its position in a gravity field) into Kinetic energy (the energy of a mass in movement).
When she releases the ball what is will happen?
the ball will have kinetic energy and potential energy.
Example of kinetic energy?
Anything that had potential energy then converted to kinetic energy. A good example would a ball. If you are playing bowling and you are swinging the ball backwards and about to through it foward, the ball has potential energy. Once you release it, and while the ball is falling it has kinetic energy. The energy of the changes from potential to kinetic energy. Hope this helps XD
If a Ping-Pong ball collided with a Whiffle ball what would happen to the kinetic energy?
The kinetic energy would transfer Ping Pong ball!
What is an example for kinetic energy?
Any moving body possesses kinetic energy. For e.g if you move a ball and it starts rolling then the ball possesses kinetic enery.
