A velocity versus time graph is used to evaluate the acceleration of an object. This is done by looking at the slope of the line on the graph.
Continue ReadingA velocity versus time graph plots velocity on the y axis and time on the x axis. If the acceleration of an object is zero, the slope of the line is zero and a horizontal line is seen on the graph. If the acceleration of an object is positive, the slope of the line is positive and the line projects upward. If the acceleration of the object is negative, the slope of the line is negative and the line projects downward.

Full Answer >An object is said to have uniform velocity if the direction of motion and the rate at which the object changes its position is constant. In other words, an object with uniform velocity continues to cover the same amount of distance over the same time interval without changing its direction.
Full Answer >Because velocity is the rate of motion of an object in a specific direction, either an increase or decrease in the object's speed or a change in its direction of travel causes its velocity to change. This change in velocity is defined as an acceleration, which according to Newton's laws of motion occurs because of an unbalanced force acting on the object.
Full Answer >Kinetic energy depends on the mass and velocity of an object. When mass or velocity increases or decreases, kinetic energy follows as a positive correlation. Velocity affects the motion of an object at a greater degree than its mass.
