Can the displacement be greater than the distance travelled by the object?
Yes
No
Which type of speed does the speedometer of a car measures?
Average speed
Instantaneous speed
Uniform speed
Increasing speed
A person has completed a round of a circular path. What is the total distance & displacement travelled by the person.
Distance = circumference of a circle; Displacement = radius of a circle.
Distance = circumference of a circle; Displacement = diameter of a circle.
Distance = diameter of a circle; Displacement = 0
Distance = circumference of a circle; Displacement = 0
The odometer of a car reads 5000 km at the start of a trip and 5600 km at the end of the trip. If the trip took 3 hour, Calculate the average speed of a car.
100 km/hr
200 km/hr
300 km/hr
400 km/hr
What is/are the correct formula of average speed of an object?
Average speed = (u + v)/2
Average speed = (u - v)/2
Average speed = total distance / total time
Average speed = total time/ total distance
What does the given (velocity - time) graph represents?
Uniform acceleration
Increasing acceleration
At Rest
Constant velocity
A bus decreases its speed from 90 km/hr to 54 km/hr in
5 sec. Find the acceleration of the bus.
( - 1 m/s2)
( - 2 m/s2)
( - 3 m/s2)
( - 4 m/s2)
Suppose a boy is enjoying a ride on a merry-go-round which is moving with a constant speed of 10 m s–1. It implies that the boy is -
At Rest
Moving with no acceleration
In accelerated motion
Moving with uniform velocity
Area under (v-t) graph represents a physical quantity which has the unit
m2
m
m3
ms-1
Which of the following figures represents uniform motion of a moving object correctly?
Graph (a)
Graph (b)
Graph (c)
Graph (d)
A car starting from rest attains a velocity of 90 km/hr in 50 sec. Assuming that the acceleration is uniform (i) the acceleration & (ii) distance travelled by the car.
a = 1 m/s2. & s = 500 m
a = 0.5 m/s2. & s = 500 m
a = 1 m/s2. & s = 625 m
a = 0.5 m/s2. & s = 625 m
Four cars A, B, C and D are moving on a levelled road. Their distance versus time graphs are shown in the given Figure. Choose the correct statement.
Car A is faster than car D
Car B is the slowest
Car D is faster than car C
Car C is the slowest
Calculate the total displacement travelled by the object in a given graph.
200 m
240 m
300 m
340 m
A ball is gently dropped from a height of 20 m. If its velocity increases uniformly at the rate of 10 m/s2., with what velocity will it strike the ground? After what time will it strike the ground?
v = 20 m/s; t = 10 sec
v = 10 m/s; t = 20 sec
v = 20 m/s; t = 2 sec
v = 10 m/s; t = 10 sec
Sam while driving to school, computes the average speed for his trip to be 20 km/h. On his return trip along the same route, there is less traffic and the average speed is 30 km/hr. what is the average speed for Sam’s trip?
32 km/hr
24 km/hr
25 km/hr
60 km/hr
