changes in speed or direction or both
speed and direction
The velocity of a car can change by increasing its speed, such as accelerating when pressing the gas pedal, or by decreasing its speed, such as decelerating when applying the brakes.
Velocity changes when the direction of the motion changes.
To find the change in velocity in a given scenario, subtract the initial velocity from the final velocity. The change in velocity is the difference between the two velocities.
An object can accelerate by speeding up (increasing velocity) or by changing direction (experiencing a change in acceleration).
Velocity can change by either changing the speed of an object or changing its direction of motion. If an object speeds up or slows down, its velocity will change. Similarly, if an object changes its direction, its velocity will also change.
Two ways: If the change in velocity is the result of hitting something, use the Momentum Equation. If the change in velocity is the result of applying a force, use the Impulse Equation. You probably mean this equation, which is: FT = m(Vf - Vo) Or, An object of mass "m" will change from velocity "Vo" to velocity "Vf" if the force "F" is applied for "T" seconds.
To find rate of change. Two common examples are: rate of change in position = velocity and rate of change of velocity = acceleration.
two things that describe velocity is distance and time.
the velocity of an object changes when it speeds up or slows down.
You change momentum by changing mass or, more commonly, velocity.
The change in velocity is 15 m/s left.
