formulae to find velocities

. Let them cover equal distances in equal intervals of time i.e., their speed is the same. Can you tell where each of them would be after say 20 seconds? P and Q can move in any direction. To locate the exact position of P and Q we require their direction of motion als..

The distance traveled by a wave in one second is termed as its velocity, it is generally denoted by the letter 'c..

Figure below gives different routes that Jack can choose from his house to school. Jack goes regularly to school by car, with an average speed of 60 km/hr. Is it possible to find out the time required to reach the destination? Yes, you can definitely find out the time using the ..

Velocity is defined as the distance travelled in a specified direction in unit time. The distance travelled in a specified direction is displacemen..

Uniform Velocity and Non-uniform Velocity - Imagine that two athletes Tom and Harry are running with a uniform speed of 5 m/s on a straight line and circular track respectively. For a layman both Tom and Harry are moving with uniform velocity but for a physicist only T..

Escape Velocity - All bodies when projected vertically upwards fall back to earth due to the earth's gravitational pull. The maximum height attained by a body depends upon the initial velocity of the body. This does not mean that no object can escape earth's gravitational pull. ..

Critical Velocity - Critical velocity is the velocity of a liquid flow upto which its flow is streamlined and after which its flow becomes turbulent. The critical velocity depends on coefficient of viscosity ' h ', density of the liquid ' r ', and radius of t..

Critical velocity is the velocity of a liquid flow upto which its flow is streamlined and after which its flow becomes turbulent. The critical velocity depends on coefficient of viscosity ' h ', density of the liquid ' r ', and radius of the tube (r). Using the methods..

Suppose a particle P is moving in a circle as shown below. Let O be the centre and OX be the X-axis. The position of the particle may be described by the angle q . Let the particle move to the position q + d q in a time dt. Assume that the particle keeps changing its position. Thus, we can def..

The velocity with which, an object circles the Earth in a circular path is known as orbital velocity. Let a body of mass m be projected from the Earth's surface so that it revolves around it. Let its height be h from the surface of the Earth. The centripetal force required make..
