1.What is the unit for kinetic energy? 2.A collision in which kinetic energy is conserved is called what? 3. It takes no work to hold a cheerleader in the air, as shown here. If no work is done by the cheerleaders, why do they eventually tire? A.The concept of work, as it apples in physics, does not apply to any process that involves people. B.Their bodies expend chemical energy as their muscles function; this is "hard work," but not the...

1. Show that the Kinetic Energy and the Momentum are conserved in this system. (Remember that momentum is a vector, so you need to show the conservation of the momentum in x and y directions separately.) Data: Before the collision: m1= 1kg v1x =1 m/s v1y=0 m/s m2=1kg v2x=-1m/s v2y=0 m/s After the collision: m1= 1kg v1x =-0.778 m/s v1y=-0.629 m/s m2=1kg v2x= 0.778 m/s v2y=0.629 m/s 2. From the data, calculate the direction(angles) of the final velocities of the...

2. Describe Kinetic Energy and Potential Energy. Describe the Law on Conservation of Mechanical Energy. If an object that is thrown perpendicular to the ground by neglecting the friction is required to go up to 125 m height, what should be the initial velocity of the object? Take the acceleration of gravity 10 m / s and assume that the mass of the object does not change.

I swung a pendulum and calculated kinetic and potential energy, however it failed to show conservation of mechanical energy. A graph of mechanical energy showed sinusoidal curves. What could explain this? It seems as though it is not only friction or air resistance, as it is not a negative slope. Please help!

1) can an object bothbhave kinetic energy and gravitational energy at the same time? Explain. 2)if an object has 6J of gravitational energy, in what process can it do 6J of work? 3) if a spring has 6J of elastic energy, in what process can it do 6J of work? Please help me answer the previous questions( I will give a good rating) thank you!
