Potential energy due to gravity = Ep = mgh [symbols have their usual meaning ]
Evidently, HALVING the mass will make Ep , HALF its previous value. So, It will be halved.

An Athelete run some distance before taking a long jump because by running the Athelete gives himself larger inertia of motion.

Hope this helps .....
Answer:
Explanation:
If no one can see it because the lights were out. Did the flea really jump?
What do you want here?
Max height (2.2sin21)²/ 2(9.8) = 3.2 cm
Time of flight 2(2.2sin21)/ (9.8) = 0.16 s
distance of flight (2.2cos21)(0.16) = 33 cm
You are Thomas Alva Edison. You also invented the phonograph
and the first practical movie camera. Sadly, you died almost exactly
9 years before I was born.
when no net external torque acts on the system then the angular momentum of a system becomes constant. In mechanics and physics, a torque is the spinning counterpart to a force.
The rotating counterpart of linear momentum in physics is called angular momentum. Given that the total angular momentum is conserved, or remains constant in a closed system, it is an important physical quantity. Angular momentum is conserved in both its magnitude and direction. Bicycles, motorcycles, frisbees, rifled bullets, and gyroscopes are all useful objects thanks to the conservation of angular momentum.
The torque is the ratio of the force's magnitude to the angle at which its line of action is perpendicular to the axis of rotation. The cross product of the position vector and the torque, a three-dimensional pseudovector, yields the torque for point particles.
