None of the above
- 3. Multiple Choice
Here is a displacement−time graph of a car. P, Q, R, S and T are five parts of the journey as shown in the graph. In which two parts do you think the speed of the car would be same?
In part R and part P
In part Q and part S

All of the above
- 4. Multiple Choice
What is the unit of the physical quantity represented under the area velocity−time graph?
m/s²
m
m/s
m²
- 5. Multiple Choice
Which of the following graph shows non−uniform acceleration?
- 6. Multiple Choice
In this velocity−time graph, what will be the displacement between 10 to 15 seconds and acceleration between position B and E.
S= 150 m a = − 4 m/s²
S= 150 m a = 4 m/s²
S= 125 m a = 20 m/s²
S= 125 m a = −20 m/s²
- 7. Multiple Choice
Draw a velocity- graph from the following information. A ball from rest at the top of a hut moves with constant acceleration for 5 seconds and attains a velocity of 15m/s. After that it travels at constant speed for 15 seconds. After which it decelerates for 10 seconds at a constant rate of 1 m/s².Then it rolls for 20 seconds at a constant speed.
