Which of the two velcotiy and acceleration, gives the direction of motion of the body? Explain.

Can a constant acceleration change the direction of motion of an objet?

Given an example of each acceleration is in the direction of motion.

What is the direction of acceleration?

Given an example of each acceleration is against the direction of motion.

Which type of force is required to change the direction of motion of the body - a balanced or unbalanced force ?

Read each statement below carefully, and state, with reasons, if it is true or false :- During rolling, the force of friction acts in the same direction as the direction of motion of the CM of the body.

Can a body have acceleration in one direction and velocity in another direction?

If the force acting on the object is not in the direction of motion then how will you consider the work done ? Explain giving example and also tell when will the work done be minimum and when it will be maximum ?
