Question

*Answer the following questions:-

Q1. What do you mean by free fall and what kind of motion a body possed under gravity .

Q2. Explain the difference between Scalar and Vector quantities

Q3. State which of the following situations are possible and give an example for each of these: (a) an

object with a constant acceleration but with zero velocity (b) an object moving with an acceleration

but with uniform speed. (c) an object moving in a certain direction with an acceleration in the

perpendicular direction.

Q4. Describe an activity to explain different types of motion.

Q5. Joseph jogs from one end A to the other end B of a straight 300 m road in 2 minutes 30 seconds

and then turns around and jogs 100 m back to point C in another 1 minute. What are Joseph’s average

speeds and velocities in jogging (a) from A to B and (b) from A to C?​

Answer 1

answer 1 :- Free fall is the motion of a body where its weight is the only force acting on an object.

answer 2 :- A quantity that has magnitude but no particular direction is described as scalar. A quantity that has magnitude and acts in a particular direction is described as vector.

answer 4:- According to the nature of the movement, motion is classified into three types as follows: Linear Motion. Rotary Motion. Oscillatory Motion.
