Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating ...

For the constant negative acceleration graphs the initial displacement is negative and the initial velocity is positive. The velocity time graphs give all three variables for motion–velocity ...

When they switched back to the slow motion view, their timing was off. You can see this in a graph of position ... assumption that the bullet has a constant velocity in the horizontal direction.

Do the birds have a constant vertical acceleration? Do they have constant horizontal velocity ... the vertical motion? Oh, I forgot to point out that the missing data in the graph is from where ...

That situation is described by Newton's Second Law of Motion. Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity ...
