If we assume there is no air resistance, this means that the horizontal component of the ball's velocity won't change. Resolving horizontally we can see that the horizontal velocity = ucos(θ). We can ...
relevant equations: F = k*x F is force, k is spring constant and x is displacement from equillibrium.
W = 1/2kx2 W is work done.
rearranging F = k*x and using t...
Atmospheric pressure is an expression for the force exerted on a surface (in this case the water surface) per unit area caused by air particle collisions on the surface. In a cup of water, there is a unif...
Free vibrations involve no transfer of energy between the vibrating object and its surroundings, whereas forced vibrations occur when there's an external driving force and thus transfer of energy between ...
It is a frame of reference in which Newton's first law, which states that objects won't change velocity (accelerate) unless an external force acts upon them, is obeyed.
