It changes more from 20 km/h to 30km/h.
-Answer from Penn State University Physics 001 Homework
A quantity with a negative rate of change becomes smaller as time goes on. A quantity with a positive rate of change becomes larger as time goes on.
Price goes from 12 to 9 means the change is -3 -3 as a percentage of 12 is 100*(-3)/12 = -25 %
Wind speed effects how much energy a windmill produces. The faster the windmill goes, the more energy it produces.
It goes: 560/80 = 7 times
It goes 26/2 = 13 times
potential energy that converts to kinetic energy
It is kinetic. Someone/something going from its gravitational (not moving) energy to then moving, creates kinetic energy, because it goes from stationary to moving. GRAVITATIONAL ------> KINETIC
the skateboards potential energy becomes kinetic energy and heat energy.
When any substance goes from solid to liquid to gas, the kinetic energy of the molecules increases.Molecules in the gaseous state have the most kinetic energy.Molecules in the solid state have the least kinetic energy.
no, kinetic energy is the energy below so if u hold a ball up in the air it has most potential energy but if u drop the ball the potential energy goes down and the kinetic energy goes up.
Kinetic
Mechanical energy is a combination of its potential and kinetic energy. For example when a goes forward that is potential energy when it stops that is kinetic energy. thanks(:
Usually in the form of increased or decreased kinetic energy of the molecules and added or reduced inter-molecular potential energy. Which way it goes depends on the direction of change in state.

At the top of the first hill, the coaster car has stored the maximum amount of potential energy. This is shown in the equation for potential energy, PE=mgh, where h is the height. The greater the height, the greater the potential energy. During the drop, potential energy is being converted into kinetic energy. The equation for kinetic energy is KE=(1/2)mv^2, where v is the velocity of the coaster car. The faster the car is going, the greater the kinetic energy. So as the car goes faster, the kinetic energy grows. But as the car goes down, h is getting lower, lowering the potential energy.
Kinetic energy of a substance is the energy of motion of its particles. Temperature is a measure of this quality. When you increase the kinetic energy of a substance, you increase the motion and collisions between its particles, and its temperature goes up.
