Which of the two ,velocity and acceleration, gives the direction of motion of the body . Explain it with the help of an illustration.

Which of the two , velcity and acceleration, gives the direction of motion of the body . Explain it with the help of an illustration.

Is the direction of acceleration same as the direction of velocity ?

Can force determine the direction of motion ? Direction of acceleration ?

Can the direction of motion of a body change if its velocity is changing at uniform rate ?

y component of velocity is 20 and x component of velocity is 10 . The direction of motion of the body with the horizonatal at this instant is

Velocity-time graph for the motion of a certain body is shown in fig. Explain the nature of this motion. Find the initial velocity and acceleration and write the equation for the variation of displacement with time. What happens to the moving body at point B? how will the body more after this moment?

Assertion : Kinematic equations are exact and are always correct. Reason : The definitions of instantaneous velocity and acceleration are true only for motion in which the magnitude and direction of acceleration are constant during the course of motion.

In negative acceleration, the velocity of a body____
