If marble rolls across the table does it posses potential or kinetic energy?
The equation is K.E. = ½ * mass * velocity2 Kinetic energy is a measure of an object's energy due to the fact that has mass and is moving. So as long as the ball has mass and is moving, it has kinetic energy. Since all tables have friction the marble will slow down as to rolls and lose some KE. Potential Energy = mass * acceleration due to gravity * height. However since the ball is on a table (height), it also has potential energy. If one end of the table is a little higher than the other, it will gain potential energy as it rolls up the little hill, of course as it rolls up that little hill, it will lose the same amount of kinetic energy as the potential energy it gained. This is called "Conservation of Energy".
How does kenetic and potential energy affect soccer in general?
In soccer, you have a soccer ball. The ball has potential energy. When you kick the ball, the potential becomes kinetic energy and the ball moves. However, your foot has potential energy as well (all matter has potential energy because all matter has the potential to move). When you kick with your foot that potential energy becomes kinetic energy. When the soccer ball is on the ground it actually has no potential energy because potential energy is only associated with height. When the ball is kicked however the kinetic energy from the player is passed on to the ball. That kinetic energy makes the ball move. If the ball is kicked into the air then the kinetic energy is passed on and some of that kinetic energy transforms into potential energy and kinetic.
What is the embryonic stage in which the embryo consists of a hollow ball of cells?
the hollow ball of cells is called the Blastocyst. At which point this occurs depends on the particular species.
Energy can be formally defined as?
Kinetic energy is the amount of energy in an object due to its motion. It is defined as the amount of work that was required to accelerate the object from rest to its current velocity. In classical Newtonian physics, kinetic energy is calcualted in the following equation.Ek=1/2mv2Where:Ek is the kinetic energy of a body;m is the mass of the body; andv is the velocity of the body.Note that kinetic energy is always relative to the observer's frame of reference. For example, a girl holding a ball still would tell you the ball has no kinetic energy, because it is not moving - it has a velocity of zero, and according to the above equation, the kinetic energy must also be zero. Even if she were in a moving car holding the ball, she would still tell you (correctly) that the ball has no kinetic energy, because from her perspective, the ball is not moving. But from a bystander's perspective on the sidewalk, the ball (and the girl, the car, etc.) would indeed have kinetic energy, because, from the bystander's frame of reference, the ball is moving.
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).
When a ball rolls down a hill what wasted energy conversion occurs?
Potential energy to kinetic energy
When a ball rolls down the hill what energy occurs?
The situation is similar as when an object falls. Potential energy is converted to kinetic energy (including rotational energy in this case); part of that kinetic energy is converted to heat energy.

What is true about the total energy of a ball as it rolls down a hillside?
It is conserved. The potential energy of the ball sitting at the top of the hill is converted into kinetic energy of the rolling ball.
What kind of energy does a bowling ball have as it rolls toward the pins?
Kinetic.
Johanna is studying what happens to the energy as a ball rolls down a ramp. What is she studying Check all that apply.?
Chemical energy
A dropped ball doesn't bounce back to its starting height how does this situation fit the law of conversation of energy?
According to the scientific law of conservation of energy the energy can be sustained by the bouncy ball indefinitely
Why does a rolling ball eventually stop even if it dosent hit anything?
Friction The ball deforms and un-deforms as it rolls, using up energy.
Why is the momentum of a billiard ball change as is rolls on a billiard table?
The answer is rather simple. Even though a billiard ball is smooth, when it rolls it imparts some of its kinetic energy to the felt covering of the table. That is, the felt heats up a bit as the ball slows down.
What happens to the potential energy and the energy of a ball as it rolls down a hill from a position of rest at the top of the hill?
The potential energy gets less until the ball gets to the bottom of the hill, at which point the potential energy is zero. The potential energy that is lost, gets converted to Kinetic energy of the ball that goes faster and faster as it gets more and more of the Potential energy.
