When does kinetic energy increase?
The kinetic energy (Ek) of a moving object will increase if it's mass (m) or velocity (v) increases.The equation for calculating kinetic energy in Newtonian mechanics is shown below.Ek = 1/2 m x v2Where it can be seen that variations in mass have a much smaller effect on kinetic energy than variations in velocity.
How can you tell that the kinetic energy is decreasing as the juggler pin rises?
The fact that the juggler's pin rises to a point and then falls back down is an indication that the kinetic energy decreases as the pin rises. At the highest point reached by the pin, its motion stops and it hangs in the air for a short moment, at which time kinetic energy is zero, and potential energy is at its maximum.
How does elastic energy changes to potential energy?
''how does elastic potential energy work in a ball?'' can you just tell me now at school. and who are you,are u just a computer and they put everythink in you or what are you some smart guy/girl
What energy transformation takes place when a bell rings?
Mechanical energy is converted into sound energy
What does Bernoullis Principle tell in regards to Pressure of a moveing fluid?
The Statement: For the streamline flow of an ideal fluid,the sum of the potential energy,kinetic energy and the pressure energy per unit mass remains constant.
How can you tell that a ball's kinetic energy has increased?
Probably because it's moving faster.
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.

How can you tell from the path of the ball that there is another force acting on the ball other than the kicking force?
Inthe kicking force, kinetic energy is acting on the ball together with Gravitational Potential Energy. Whereas the part where aother force is acting on iit while the ball is not moving is alsoocontrolled by gravitaitional potential energy.
How can you tell kinetic energey and potential energy apart?
Potential energy is energy that is soon to become kinetic energy.Say there is a rock on the top of a hill.That is potential energy.When it falls it becomes kinetic energy.
How do you tell if an energy transfer is kinetic or potential?
If a body is slowing down, the transfer is potential energy. I a body is speeding up, the transfer is kinetic energy.
How can you tell when some thing has energy?
You can tell if has thermal energy by its temperature, and you can tell if it has kinetic energy because it is moving. But you can't easily tell what materials will release chemical energy or nuclear energy, without doing scientific tests on them.
What does the temperature tell you about the particles of a substance?
Temperature is the measure of the internal kinetic energy of a body.
How can you tell that the kinetic energy is decreasing as the juggler pin rises?
The fact that the juggler's pin rises to a point and then falls back down is an indication that the kinetic energy decreases as the pin rises. At the highest point reached by the pin, its motion stops and it hangs in the air for a short moment, at which time kinetic energy is zero, and potential energy is at its maximum.
When a gas is heated does all of the absorbed energy convert to kinetic energy If not please tell what it is converted to part kinetic and part potential energy or just potential energy?
The gas will have thermal energy given by its specific heat capacity (at constant pressure or volume depending on the situation) times the rise in temperature. This thermal energy is possessed because of the increased kinetic energy of its molecules, due to the rise in temperature.
How much should be the mass of a man who has kinetic energy 625 j?
You can't tell from that much information. The kinetic energy of any object depends on its mass and its speed. So there are three quantities involved ... kinetic energy, mass, and speed. In order to calculate any one of them, you have to know the other two.
