Is mass of a body is reduced to half and its velocity is doubled its kinetic energy is?
The energy of a body depends on mass and velocity. Kinetic energy is equal to half of the product mass and velocity. SI unit is joules. 1) If mass doubled then kinetic energy also gets doubled.
What happens to kinetic energy when velocity is doubled and mass is halved?
2..if velocity doubled with constant mass then kinetic energy becomes 4 times the initial kinetic energy.. 3..if mass doubled and velocity reduced to half kinetic energy will be half the initial value..
Is the mass of a body is doubled and its velocity becomes half then the linear momentum of the body will?
When the mass of the body is doubled , mass is 2M and the when the velocity becomes half the velocity is V/2. Hence the momentum of the body is ½MV².
When mass is doubled and velocity is doubled what will happen to the value of kinetic energy?
Answer and Explanation: The kinetic energy of the object is directly proportional to the mass, therefore on doubling the mass kinetic energy will also become double.
What happens when mass is halved?
If an object’s mass is halved its acceleration will be doubled as long as the force acting on the object remains constant.
What happens to the kinetic energy of a body if its mass is halved?
KINETIC ENERGY WILL INCREASE WHEN MASS IS HALVED..
What happens to kinetic energy when mass is half?
What happens to the kinetic energy if the velocity of the object is reduced to half?
If we halve the object’s velocity, we’re saying that the final velocity is 12 the initial velocity, or in symbolic terms, vf=12vi . ∴ We can see that the final kinetic energy of the object is 14 of the kinetic energy initially possessed by the object.
When velocity of a body is doubled and mass is reduced to half it’s linear momentum becomes twice?
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 mass of a body and its velocity both are doubled then the percentage change in its linear momentum is?
Kinetic energy of a body of given mass, is directly proportiional to its square of its velocity. When momentum is doubled, mass remaining constant, this means velcity is doubled. Hence, kinetic energy becomes 22=4 times i.e. say from 100 units to 400 units. and percentage increase in kinetic energy is 400−100=300\% .
What will happen to Ke of the body if the mass is reduced to half?
Answer: Expl: New KE = 1/2. (2v)^2 = mv^2 = Double of Original KE KE will get doubled.
When mass is halved and velocity is doubled?
Question: If the mass of the body is halved and its speed is doubled, what happens to the kinetic energy of the body? Answer: 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.
What happens to kinetic energy when mass is halved and velocity doubled?
Kinetic Energy remains constant. KE= 1/2mv^2 Now, if mass is halved and velocity is doubled, new K.E would be, KE1= 1/2 x (1/2m) x 2v^2 or, KE1= 2/4mv^2 or, KE1= 1/2mv^2 Thus, KE= KE1 Ans: KE will get doubled.
What is the formula for kinetic energy of half mass?
K.E2=1/2 (2) (10^2), =1/2 (2) (100), =1/2 (200), K.E=100 Joules of Energy. As you can see, when the body of mass is halfed and its velocity is doubled compared to another body of mass in motion, it’s Kinetic Energy will be doubled compared to the first body of mass in motion.
How do you calculate kinetic energy from mass and velocity?
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.
