Does a golf ball have the same momentum as a baseball?
A baseball and a golf ball have the same momentum. Which has the greater kinetic energy? When the velocity of an object is doubled, by what factor is its momentum changed? By what factor is its kinetic energy changed? a. The momentum is increased by a factor of 4 and the KE is doubled. b.
What happens when kinetic energy is twice the speed?
If it moves at twice the speed, its kinetic energy is four times as far. twice as far. momenta. times. masses. forces. because velocity is conserved. when momentum is conserved. if the masses of the bullet and gun are equal. when both velocity and momentum are conserved. impulse.
What are the factors that affect kinetic energy?
If it moves at twice the speed, its kinetic energy is four times as far. twice as far. momenta. times. masses. forces. because velocity is conserved. when momentum is conserved. if the masses of the bullet and gun are equal. when both velocity and momentum are conserved. impulse. force. distance that a force acts.
What happens to momentum when velocity is tripled?
If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.
When the speed of a car is tripled its kinetic energy changes by a factor of?
For a threefold increase in speed, the kinetic energy will increase by a factor of nine. And for a fourfold increase in speed, the kinetic energy will increase by a factor of sixteen. The kinetic energy is dependent upon the square of the speed.
When the velocity of an object is quadrupled by what factor is its kinetic energy changed?
Answer and Explanation: If the velocity of an object is quadrupled then the momentum will also change by a factor of four.
What would happen to the kinetic energy of the object if you tripled the velocity of the object?
1 Expert Answer 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.
When momentum of an object is tripled what happens to its kinetic energy?
Hence, if the momentum of a body is tripled, it's Kinetic energy will become nine times its original value.
What happens if kinetic energy is tripled?
Answers and Solutions. Question: What happens to kinetic energy when velocity of a body is tripled? Answer: as we know K.E=1/2mv^2 from this eqn we get K.E is directly proportional to square of velocity of body so, if we triple the velocity of body the K.E will become nine times of the initial K.E.I hope you got it.
What happens to momentum when kinetic energy is quadrupled?
If the KE of the body is quadrupled then the momentum of the body doubles.
When the speed of your car is doubled by what factor does its kinetic energy increase?
When the speed of your car is doubled, by what factor does its kinetic energy increase? Therefore when you double the velocity, that value is then squared. Therefore your kinetic energy is increased by 4 times the original amount.
When velocity of a body is increased 5 times what is the change in its kinetic energy?
velocity of a body is increased by 5 times what happens to its kinetic energy? Formula for kinetic energy is 1/2 m v^2 If velocity of a body is increased by 5 times, then v^2 will increase by 25 times but mass is still of body as it is not changing. So, kinetic energy will increase by 25 times.
What will happen to the kinetic energy if the velocity is doubled?
Hence, when velocity is doubled, kinetic energy becomes 4 times.
What will happen to the momentum of an object if the velocity increases?
Momentum is directly proportional to velocity. If momentum of an object is doubled , but its mass does not increase (so velocity remains below the speed of light) then its velocity is doubled. If the velocity is doubled, then the kinetic energy increases by four times.
When mass and velocity are tripled then the kinetic energy increases by?
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. Hence KE is 9 times greater.
What happens to kinetic energy when speed is doubled?
The kinetic energy is proportional to the square of the speed, so doubling the speed increases the kinetic energy by a factor of 4.
When a car's speed is doubled its kinetic energy is?
This means that when the velocity of an object doubles, its kinetic energy quadruples. A car traveling at 60 mph has four times the kinetic energy of an identical car traveling at 30 mph, and hence the potential for four times more death and destruction in the event of a crash.
What factors affect the kinetic energy answer?
Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed.
What happens to kinetic energy when velocity is tripled?
Since KE = (1/2) mv^2, if velocity is tripled, kinetic energy would be multiplied by 3^2=9; at the same time, if mass is halved, the same would happen to KE. Summing up, in the case under consideration, kinetic energy would be increased by a factor 9/2, that is 4.5.
How to find kinetic energy?
The formula for kinetic energy is KE = 1/2 mv^2. When the mass is reduced to 1/2 of m and the velocity is reduced to 1/2 v then the new kinetic energy is KE = 1/2 * 1/2 m * (1/2 v)^2. Simplifying the new KE is 1/2 * 1/2 * 1/4 mv^2. Further simplification results to KE = 1/2 mv^2 * 1/8.
How fast can a particle accelerate?
We can accelerate any particle to 99.999999…..% of the speed of light, and that's what’s happening in the LHC, CERN.
Which particle has the least mass?
Neutrinos have much less mass than any other known particle that has any mass at all. There are three types of neutrinos, and we know from various neutrino detection experiments that they are all much less massive than electrons, but we don't know for sure which has the least mass.
Is KE proportional to mass?
KE is directly proportional to the mass and the square of the velocity, so velocity is more significant.
Answer
Kinetic energy would increase by a factor of 4 where as momentum would increase by a factor of 2.
