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:
Since these two forces are of equal magnitude and in opposite directions, they balance each other. The book is said to be at equilibrium. There is no unbalanced force acting upon the book and thus the book maintains its state of motion. When all the forces acting upon an object balance each other, the object will be at equilibrium; it will not accelerate.
Explanation:
Answer:
When one system vibrating at its natural frequency is put closer to a stationary system, the stationary system receives impulses.
At resonant frequency, the system vibrating at its own natural frequency suddenly goes on decreasing in order to cope with neighboring system.
These decrease in frequency is known as damping.
