What is the formula for velocity? Vector Form of Speed: The quantities such as mass, speed, electric current, velocity, acceleration, etc. are classified into two categories. These categories are vectors and scalars. The vectors are such type of quantities which are defined completely if we kno...
Velocity is defined as the time rate of change of the position of an object relative to an arbitrary reference point. As a vector quantity, the velocity quantifies the magnitude and direction of how fast an object is moving.Answer and Explanation: ...
But it is typically used to mean lots of different things - like pushing, energy, speed, and even momentum. In physics, we have a very explicit definition for momentum. The momentum (at velocities not near the speed of light) is defined as the product of the mass and velocity of an ...
1. Introduction One of the achievements of the special theory of relativity is the statement about the equivalence of mass and energy in a sense that the mass of a body increases with its energy including kinetic energy; therefore, the mass depends on the velocity of the body. This ...
A ball is kicked from the ground at 30 m/s at an angle of 37° and lands on a roof 72 meters away. a. How high is the roof? b. What is the velocity of the ball just before it hits the roof? Projectile Motion In our daily lives, we encounter motions that are not conf...

Know what is angular velocity in detail along with examples at BYJU'S. Angular velocity refers to how fast an object rotates or revolves relative to another point.
A test particle that is kept stationary in the inertial frame and then released will immediately start to curve towards the proper position of the moving mass and not towards the position where the mass was, taking into account the finite speed of light. Now this is totally unremarkable, bec...
