free fall and horizontal fall in physics

When the card is flicked with the finger the coin placed over it falls in the glass But the horizontal distance travelled by a projectile depends upon its velocity in the horizontal direction. The horizontal distance travelled by a projectile depends upon its..

The collimator renders a parallel beam of light through the two coaxial cylindrical tubes. One end of the collimator has a slit through which light enters the tube and falls on lens L situated at the other end. Prism table is a circular plate fixed over a vertical stand of adjustable..

Scattering Due to Polarisation - When a light wave falls on a transparent solid, it causes the electrons in the solid to oscillate periodically in response to of the incident waves. Since these oscillating charges act coherently or cooperatively there is a lack of scattering of light. But..

We know by Newton's laws that Consider the case of sand falling vertically on a horizontal conveyor belt moving at a velocity 'v'. The external force on the belt is in the direction of the velocity v. The mass of the belt is not considered as it is moving at ..

The above figure shows a body moving with uniform speed along a circle. Let perpendiculars be drawn from different positions of the body onto any diameter, say the vertical diame..

(shape resembling a sin e cu rve) is generated. Let a long spring (also called a slinky) be placed horizontally on a smooth floor with one end of it resting against a wall. On giving a sudden flip to the free end of the slinky so as to compress it, a compressional wave is found ..

When the body is at position C, its height above the ground may be regarded as zero. Therefore, potential energy of the body = 0. If v c is the velocity with which the body touches the ground, then v c 2 - 0 = 2gh v c 2 = 2gh Total energy of the body = mgh From the above illustration, it..

. If the intensity becomes too great, the sensation becomes one of pain rather than of hearing. This is indicated by the upper curve which lies close to 10 6 m Wm -2 or 1 Wm -2 , putting 1 = 1 Wm -2 and I 0 = 10 -12 Wm -2 in equation (1-35), we get = 10 log 10 12 = 120 dB A sound of intensity level..

Falling Objects and Acceleration due to Gravity - We know that whenever an object is dropped from a height, it falls towards the Earth. Similarly, when an object is projected vertically upwards, it goes up but after attaining a certain height, it starts falling down. I..

Aristotle, the great ancient philosopher performed some experiments to study the speed of freely falling objects. He observed that when two bodies of different masses were dropped simultaneously from the same height, the heavier object reached the Earth's surface earlier than the lighter ..
