What happens to the kinetic energy when the speed is tripled?
If the speed triples, how does the kinetic energy change? The kinetic energy increases as the square of the speed. If the speed triples, how does the kinetic energy change? The kinetic energy increases by a factor of 9.
What is the kinetic energy if the mass is tripled and the speed is tripled?
1 Expert Answer a)So if the mass triples then the KE triples too. The relationship between Kinetic Energy and velocity is also directly proportional but with the square of the velocity. b) So if the velocity triples, then it is 32 , three squared or 9. Hence, KE is 9 times greater.
What will happen to the kinetic energy if the speed will be doubled?
The change in the kinetic energy of the object as the speed changes is proportional to the square of the factor by which the speed changes. If the speed of the object becomes double, its kinetic energy changes to four times the initial kinetic energy.
What is the kinetic energy if the velocity of the ball is tripled?
This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. For a threefold increase in speed, the kinetic energy will increase by a factor of nine.
What happens to the potential energy if the mass is constant and the height is tripled?
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.
When the speed of the truck is tripled by what factor does its kinetic energy increase?
nine
For a threefold increase in speed, the kinetic energy will increase by a factor of nine.
What happens to an object’s kinetic energy if the mass is tripled and the speed is quadrupled?
For example if the speed of the object becomes double, its kinetic energy changes to four times the initial kinetic energy. Similarly, if the speed of the object triples the kinetic energy becomes nine times the initial kinetic energy.
What happens to potential energy when mass is constant and height is tripled?
What is the kinetic energy if the mass is reduced to 1 2 and speed is doubled?
Answers and Solutions Let, mass=m, speed=v KE1= (1/2)mv^2 now, mass= m/2, speed= 2v KE2= (1/2). (m/2)(2v)^2=mv^2=2KE1,i.e., double of initial energy. Answer: Expl: New KE = 1/2.
