What is the greatest potential energy?
gravitational potential energy
What is the pair of quantities are the factors that affect kinetic energy?
The amount of translational kinetic energy (from here on, the phrase kinetic energy will refer to translational kinetic energy) that an object has depends upon two variables: the mass (m) of the object and the speed (v) of the object.
Which is the following quantities has the greatest influence on the amount of kinetic energy of a car while traveling on a highway?
It turns out that an object’s kinetic energy increases as the square of its speed. A car moving 40 mph has four times as much kinetic energy as one moving 20 mph, while at 60 mph a car carries nine times as much kinetic energy as at 20 mph. Thus a modest increase in speed can cause a large increase in kinetic energy.
What change should be affected in the velocity?
Kinetic energy is directly proportional to the product of mass and square of the velocity of the body. Kinetic energy increases with an increase in mass; to keep it the same to its initial value, we have to reduce the body’s velocity.
What should be the change in velocity?
∴ The velocity of a body should be halved, if its mass is increased by four times for the same K.E. of the body. Was this answer helpful?
How much work is needed to be done on a ball of mass 50 gram to give it a momentum of 5 kgm s?
How much work is needed to be done on a ball of mass 50 g to give it a momentum of 5 kg m s-12 Ans. 250 J.
How much work will be done on a ball of mass 50 gram to give it a momentum 500 g/cm 1?
5×104J.
What will be the change in Ke if the velocity increases to 4 times its original value?
If KE increases to 4 times its initial value , momentum increases to 2 times its initial value. Hence final momentum is 100% more than the initial momentum. The momentum of a body increases by 20%.
Why does mass change with velocity?
As an object increases in speed, so does the amount of energy that it has, this energy is what we refer to as ‘the increase in mass’ (just remember, this is inertial mass). Since an object has infinite kinetic energy when it approaches the speed of light, it therefore has infinite mass as well.
Does the charge of a body change with speed like its mass?
Why do charge on an object remains unaffected by the motion of the object? Unlike mass, the charge on an object is said to be unaffected by the motion of the object.
