what is the relation between velocity and time?
63256
velocity-time. The relation between velocity and time is a simple one during uniformly accelerated, straight-line motion. The longer the acceleration, the greater the change in velocity. Change in velocity is directly proportional to time when acceleration is constant.

Average speed is calculated by dividing the distance of an object in motion by it's time. ... The difference between speed and velocity is that velocity has direction. Both of them involve distance and time, but only velocity involves direction.

Speed, velocity and acceleration. Average speed is distance divided by time. Velocity is speed in a given direction. Acceleration is change in velocity divided by time.

One cannot move across a Distance without also moving 'through" Time. This is both a direct and parallel relationship. Speed OR Velocity = Distance / Time.

Speed and velocity both represent a way to measure the change in position of an object relative to time. In fact, for a straight line motion, the speed and velocity of an object are the same (since distance and displacement will be the same). Speed and velocity are measured in the same units: meters per second or m/s.

We also learned that speed is a scalar quantity, which is one that requires only a magnitude, while velocity is a vector quantity, which is one that requires a magnitude (also mph) and a direction. The rate of change for velocity is acceleration, which is measured in displacement over time over time (e.g., m / s^2).

Velocity is the rate of change of displacement( change of distance in a particular direction with respect to time) , and acceleration is the rate of change of velocity per unit of time. (Amount of increase or decrease in velocity). Also, speed is a scalar quantity but velocity and acceleration are vector quantities.

The average speed is the distance (a scalar quantity) per time ratio. ... On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.

Speed is a scalar quantity – it is the rate of change in the distance travelled by an object, while velocity is a vector quantity – it is the speed of an object in a particular direction.

To calculate velocity, you divide your distance traveled by the time it took to travel that distance and you add your direction to it.

Speed is the distance covered in unit time whereas velocity is the displacement covered in unit time. Speed is a scalar quantity and velocity is a vector. Speed only determines the magnitude that is how fast is a body moving whereas velocity determines the direction also that is in which direction the body is moving.

Distance and speed are scalar quantities, as they are fully described by magnitude with no reference to direction. ... Velocity can be thought of as speed with direction. The formula for speed is change in distance divided by change in time. The formula for velocity is change in displacement divided by change in time.

The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.

Average speed is distance divided by time. Velocity is speed in a given direction. Acceleration is change in velocity divided by time. Movement can be shown in distance-time and velocity-time graphs.

velocity is a vector quantity. On the other hand speed is a scalar quantity that is it has only magnitude but no direction. the speed can be only positive or zero. Whereas the velocity can be both positive negative as well as zero.

To find out something's speed (or velocity) after a certain amount of time, you just multiply the acceleration of gravity by the amount of time since it was let go of. So you get: velocity = -9.81 m/s^2 * time, or V = gt. The negative sign just means that the object is moving downwards.

Acceleration=Change in velocityChange in time. More precisely, the constant acceleration a is given by the formula. a=v(t2)−v(t1)t2−t1, where v(ti) is the velocity at time ti. Since velocity is a vector, so is acceleration.
