Q.No.1: -Why the direction of acceleration due to gravity ‘g’ is always downward? Explain with example.

Q.No.2: - Write down the basic three equation of linear motion.

Q.No.3: - If the body is moving with uniform linear velocity in magnitude but its direction is changing then it will have acceleration. Can we check this type of acceleration from v-t graph? If not then why?

Q.No.4: - If a body is moving and the graph of its acceleration is parallel to the time axis, then what will be the magnitude of the acceleration?

Q.No5.: - Under what condition instantaneous velocity and average velocity of a body becomes equal?

Q.No.7: - State Newton’s third law.

Q.No.8: - Find unit of force from Newton’s second law.

Q.No.9: - State Newton second law.

Q.No.10: - If we increase the force then acceleration increase and if we increase the mass then acceleration decrease. Drive the mathematical relation between force, mass and acceleration according to this statement.
