State whether the following statement is true or false:
$A$ body is said to be at rest if it does not change its position with respect to its reference point.

The velocity-time graph of a car is given below. The car weighs $1000 \ kg$.
$(i)$ What is the distance travelled by the car in the first $2 \ s$?
$(ii)$ What is the braking force at the end of $5 \ s$ to bring the car to a stop within one second?

Account for the following:
$(a)$ What is the shape of the path of a body when it is in uniform motion?
$(b)$ Give one example of non-uniform motion.
$(c)$ Two cars $A$ and $B$ have their $x-t$ graph as shown in the figure. Which has greater velocity?
$(d)$ What is the quantity which is measured by the area occupied below the velocity-time graph?
$(e)$ $A$ body is moving with a velocity of $10 \, m/s$. If the motion is uniform,what will be the velocity after $10 \, s$?

Out of the three speed-time graphs shown below,identify the graph for the following cases:
$(i)$ $A$ ball thrown vertically upwards and returning to the hand of the thrower.
(ii) $A$ body decelerating to a constant speed and then accelerating.

Area under a speed-time graph is equal to the

The following displacement-time graph shows the positions of a body at different times. Calculate the velocity of the body as it moves from: $(i) A-B, (ii) B-C, (iii) C-D$.
