Kinetic energy is the energy that an object has when it is in motion, so anything that will stop the motion of an object will decrease it's kinetic energy. The motion of an object can be stopped by any outside force acting on the object, whether sudden (think of stopping a rolling soccer ball with your foot -- that's decreasing it's kinetic energy), or continuous (the friction of that ball against the air and ground will eventually cause it to stop rolling on its own).
In the vacuum of space where there is no air to create friction a projectile will continue moving at the same speed without stopping and without decreasing its kinetic energy.

Objects that are able to fall have what type of energy?
When a body is supported at a height, it has potential energy. When it is released, it will start to fall. As the downward velocity increases, so kinetic energy increases. The potential energy is reduced as the height of the body decreases.
Kinetic energy is the energy of?
Motion.
Energy in the form of motion?
The energy of motion is called kinetic energy.
What are the two main forms of energy?
The two main forms of energy are Kinetic energy and Potential Energy. Kinetic energy is motion energy. Potential energy is energy stored in matter.
When does zero kinetic energy occur?
kinetic energy is zero when the body is at rest.
What will affect kinetic energy?
Kinetic energy is affected by an object's mass and its velocity. The kinetic energy of an object increases as its mass or velocity increases. Conversely, kinetic energy decreases as mass or velocity decreases.
What Explain what happens to the average kinetic energy, thermal energy, and temperature of a substance when the particles in the substance slow down.?
The particles in a substance slow down when the average kinetic energy of the particles decreases. As the average kinetic energy decreases, the internal energy decreases, and so the thermal energy decreases. As the thermal energy of the substance decreases, the temperature decreases.
If kinetic energy icreases?
if kinetic energy increases than potetial energy decreases
As the temperature of a gas decreases what change occurs in the amount of kinetic energy?
As the temperature of a gas decreases, the average kinetic energy of the gas particles also decreases. This is because temperature is a measure of the average kinetic energy of the particles in a substance.
What happens to an objects temperature if the kinetic energy of its particles decreases?
If the kinetic energy of an object's particles decreases, its temperature will decrease as well. Temperature is a measure of the average kinetic energy of the particles in a substance, so a decrease in kinetic energy means a decrease in temperature.
When a puck falls it potential energy increase or decrease?
As a puck falls, its potential energy decreases and is converted into kinetic energy due to the force of gravity acting on it. The potential energy decreases because the puck is losing height and moving closer to the ground, which decreases its gravitational potential energy.
What happens to the kinetic energy when temperature is changed?
When the temperature is increased the kinetic energy increases, and when it is decreased the kinetic energy decreases.
Does kinetic energy decreases as a box accelerates down an inclined plane?
Kinetic energy increases; potential energy decreases, because the object is now in motion
What form of energy is related to change in speed?
Kinetic energy is related to the change in speed of an object. As an object's speed increases, its kinetic energy also increases, and as its speed decreases, its kinetic energy decreases.
How is tempetature related to kinetic energy?
Temperature is directly related to the average kinetic energy of the particles in a substance. As temperature increases, the average kinetic energy of the particles also increases. Conversely, when temperature decreases, the average kinetic energy of the particles decreases.
What happens to the kinetic energy of the object?
The kinetic energy of an object increases as its speed increases, and decreases as its speed decreases. Kinetic energy is directly proportional to the square of the object's speed, meaning a small change in speed can have a significant impact on its kinetic energy.
Does the temperature decrease when thermal energy decreases?
Yes, temperature is a measure of the average kinetic energy of particles in a substance. When thermal energy decreases, the average kinetic energy of the particles also decreases, leading to a decrease in temperature.
