Q1. A modern car can develop an acceleration four times greater than an antique car like “Lanchester 1800”. If they accelerate over the same distance, what would be the velocity of the modern car compared to the antique car?

(a) Half as much
(b) The same
(c) Twice as much
(d) Four times as much

Q2. A car and a delivery truck both start from rest and accelerate at the same rate. However, the car accelerates for twice the amount of time as the truck. What is the traveled distance of the car compared to the truck?

(a) Half as much
(b) The same
(c) Twice as much
(d) . Four times as much

Q3. A car and a delivery truck both start from rest and accelerate at the same rate. However, the car accelerates for twice the amount of time as the truck. What is the final speed of the car compared to the truck?

(a) . Half as much
(b) The same
(c) Twice as much
(d) . Four times as much

(a) The object moves 5 m each second
(b) . The object’s acceleration increases by 5 m/s2 each second
(c) the object’s velocity increases by 5 m/s each second
(d) . The object’s velocity stays the same

Q5. A snapshot of three racing cars is shown on the diagram. All three cars start the race at the same time, at the same place and move along a straight track. As they approach the finish line, which car has the lowest average speed?

(a) . Car I
(b) . Car II
(c) Car III
(d) All three cars have the same average speed

Q6. An object moves at a constant speed of 6 m/s. This means that the object:

(a) . Increases its speed by 6 m/s every second
(b) Decreases its speed by 6 m/s every second
(c) Doesn’t move
(d) Moves 6 meters every second

Q7. Velocity of a body changes :

(a) If direction of motion of changes
(b) If magnitude of speed changes
(c) If both speed as well as direction of body changes
(d) If any one of above happens?

Q8. The velocity--time graph of a body when its velocity increases non uniform ly is a:

(a) straight line
(b) line parallel to x axis
(c) line parallel to y axis
(d) curved line

Q9. If the distance --time graph of a body is parallel to the time axis the body is :

(a) accelerating
(b) retarding
(c) at rest
(d) moving fast
