increasing speed
if its velocity is increasing or decreasing
If the velocity is decreasing, the object is decelerating.
initial velocity is the velocity with which a particle starts its journey.
Speed is distance covered divided by time, while velocity is displacement divided by time. Velocity is a vector quantity while speed is not. An example of when speed would be decreasing yet velocity would be increasing occurs when a car driving in reverse slows down. If it was going 30m/s and then slowed town to 10m/s, the speed would be slowing down. However, since the car is moving along the negative x axis, its initial velocity vector would be -30m/s and it would decellerate to a velocity of -10m/s. The example isn't great, but you can get the picture that the way that this is possible is by the fact that speed is a scalar quantity while velocity is vector.
Acceleration can be described as the rate at which an object's velocity changes over time. It measures how quickly the object's speed or direction is changing. Therefore, it quantifies how much an object's motion is increasing or decreasing.
if its velocity is increasing or decreasing
If the distance is not changing, the object is not moving. If the distance is increasing or decreasing linearly then the object is moving at a constant velocity. If the distance is increasing or decreasing parabolically then the object is being accelerated or decellerated.
If an object is sustaining a constant velocity it has 0 acceleration, because acceleration is either increasing or decreasing speed.
If the velocity is decreasing, the object is decelerating.
Final velocity = Initial velocity +(acceleration * time)
When an object is moved by a force, work is done, increasing or decreasing its kinetic energy, often but not always decreasing or increasing its potential energy.
Vf = Vi + at Where Vf = final velocity Vi = initial velocity a = acceleration t = time
Velocity is the measure of increasing and decreasing speed. For example... on a velocity graph, if the object being measured is gradually getting faster the line will go up. If it is getting slower, it will go down, if it is staying at a constant speed, the line will be straight
initial velocity is the velocity with which a particle starts its journey.
