What is the difference between vector and velocity?
is that vector is (mathematics) a directed quantity, one with both magnitude and direction; the (soplink) between two points while velocity is (physics) a vector quantity that denotes the rate of change of position with respect to time, or a speed with the directional component.
What is difference between constant velocity and uniform velocity?
UNIFORM VELOCITY: when an object is moving in a straight line, without any acceleration. No change in speed or direction is experienced. CONSTANT VELOCITY: when the speed of an object has not changed even though the object may have experienced a change in direction (zero acceleration).
What is called uniform velocity?
The condition in which a body covers equal distance in an equal interval of the time is known to be uniform velocity. In equation( d=v t ) v is the average velocity of a body during time t. if both its magnitude and direction do not change with time then it can be said that the body is at uniform velocity.
What is the difference between uniform and variable velocity?
A. Uniform velocity changes with time, while variable velocity doesn’t change with respect to time. Hint: When the motion of a body is in such a way that it has equal displacements in equal intervals of time, the body is said to be in uniform velocity. …
What is variable velocity?
Variable velocity is the velocity which changes with time. When a body covers unequal displacements in equal interval of time, it is said to have variable velocity.
Which has two velocity or acceleration?
Answer: It is the velocity which decides the direction of motion of a body. The acceleration simply tells the rate of change of velocity. For example, when a body is thrown vertically upwards, its direction of velocity is upwards, that is why the body goes upward, where as its acceleration is downwards.
Are velocity and acceleration directly proportional?
Velocity is directly proportional to time when acceleration is constant (v ∝ t). Displacement is proportional to time squared when acceleration is constant (∆s ∝ t2).
