what is momentum?what is velocity?
Answers
Answer:
Momentum refers to the quantity of motion that an object has.
Velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time.
Hi!
Momentum can be defined as "mass in motion." All objects have mass; so if an object is moving, then it has momentum - it has its mass in motion. The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
- Momentum = mass • velocity
Velocity is defined as a vector measurement of the rate and direction of motion. Put simply, velocity is the speed at which something moves in a particular direction, such as the speed of a car traveling north on a major freeway, or the speed a rocket travels as it launches into space.
- r = d / t
r is the rate, or speed (sometimes denoted as v, for velocity)
d is the distance moved
t is the time it takes to complete the movement
