acceleration work by speed when something is going fast and when it and go over or faster with something.
Acceleration is a change in speed or velocity. So if you going faster than your starting speed your accelerating. If your changing direction (a change in velocity) then that is also acceleration.
Acceleration occurs when there is a change in an object's velocity, either in its speed, direction, or both. This can happen due to forces acting on the object, such as gravity, friction, or propulsion. The rate of change in velocity over time determines the magnitude of the acceleration.
At a constant speed there is no acceleration. Acceleration describes a positive change in speed meaning to go faster. Deacceleration describes how fast something is slowing down. But at a constant speed of 60mph there is acceleration or deacceleration.
Going up a hill would make your acceleration decrease or cause it to be slow. Going down a hill would make acceleration increase causing you to go faster.
1.2 divided by 2 seconds equals .6m/s... i think. acceleration without speeding is when you're going in circles, but you feel like you're going faster.
a horizontal line
Make the "something" lighter when going agaiinst gravity (up).Make something heavier when going down.Make the force acting on the "something" biggerMake the "something" move easier through or on whatever it is moving through or on. Make it more aerodynamic, make any wheels spin easier etc etc.
a horizontal line
The graph of acceleration vs time for something going at a constant positive velocity would be a horizontal line at zero on the acceleration axis. This is because there is no change in velocity, so the acceleration is constant and equal to zero.
Yes, acceleration directly impacts the change in speed of a car. A higher acceleration will cause the car to increase its speed more rapidly, while a lower acceleration will result in a slower increase in speed.
If something is traveling at a "steady" speed, it can't be accelerating.
