Heat energy caused by friction is usually a waste product that results when energy is destroyed or dissappears.
Friction converts useful kinetic energy into thermal energy or heat. Friction gets a bad rap for turning useful energy into useless energy.
Answer:
The answer to the question is
Momentum
Explanation:
Momentum in physics refer to the attribute that a body has by virtue of its mass and velocity. It is found by multiplying the mass of the moving object and the velocity, hence
Momentum = Mass × Velocity = m·v
Newton first law of motion states that the force acting on an object is proportional to the rate of change of momentum produced
Therefore when we find the momentum of the two cars, the one that has the greater momentum will require the most force to stop it.
Momentum is a physics term; it refers to the quantity of motion that an object has. A sports team that is on the move has the momentum. If an object is in motion (on the move) then it has momentum
Momentum
Answer:37 J
Explanation:
Given
Step :1
Heat added Q=44 J
Work done=-20 J
Step :2
Heat added Q=-61 J
work done
as the process is cyclic
work done in compression is 37 J
Answer:
Afterdrop is the phenomenon of your body temperature continue to drop even after you get out of cold water and into a warmer environment – so that you feel colder 10 or 40 minutes after you exit than you did in the water. When you swim, your body shuts down circulation to your skin, pooling warm blood in your core.
