At Position 1: The ball has both PE and KE. (The ball is at a height from ground and velocity is given to the ball)
At Position 2: The ball has both PE and KE. (The ball is at a height from ground and velocity is also there.
At Position 3: The ball has both PE and KE. (The ball is at a height from ground and velocity is also there.)
At position 4: The ball has only PE. (The ball is at a height from ground and velocity is zero.)
At position 5: The ball has both PE and KE. (The ball is at a height from ground and velocity is also there.)
At position 6: The ball has both PE and KE. (The ball is at a height from ground and velocity is also there.)
At position 7: The ball has only KE (Just before hitting the ground). After landing the ball have neither of the energy.
Answer:
potential energy
Answer : During the winding of the spring of a clock, the kinetic energy gets converted into stored potential energy of the spring.
Answer:
The planets and moons that orbit in the solar system.
Explanation:
For example the earth moves at 67,000 mph (107,000 km/h), and is constant from the gravitational pull of the sun. The moon orbits at about 2,288 mph (3,683 km/h). these are both traveling at different velocities but at a constant speed.
Answer:
We know the momentum after the collision MUST be equal to the momentum BEFORE the collision.
Momentum is a VECTOR quantity having both magnitude and direction. The first ball has momentum P =m*v = 2*4 = 8 at 90degrees. The second ball has momentum P = 1*8 = 8 at -90 or 270 degrees. They sum to zero when you perform vector addition.
