A worker covers a distance of 40 km from his house to his place of work, and 10 km towards his house back. Then the displacement covered by the worker in the whole trip is:
Zero km
10 km
30 km
50 km
Rate of change of displacement is called:
Speed
Acceleration
Velocity
Retardation
An object travels 40m in 5 sec and then another 80m in 5 sec. What is the average speed of the object?
12 m/s
6 m/s
2 m/s
0 m/s
SI unit of Acceleration is m/s
True
False
The magnitude of a displacement of a particle can be more than the distance traversed.
True
False
Scalar quantities can be added according to the rules of arithmetic.
True
False
If a particle moves with a uniform velocity then:
The particle moves in a circular path
The particle moves in a straight line
The particle moves in a curved path
The particle is at rest
In a circular motion,
the direction of motion changes continuously
the direction of motion is fixed
acceleration is zero
velocity is zero
A particle is traveling with a constant speed. This means
it covers equal distances in equal time intervals
it does not change its direction of motion
its position remains constant as time passes
its acceleration is zero
Vector quantities can be added according to the rules of arithmetic.
True
False
If the displacement of a particle in a 10-minute time interval is zero. Then its velocity at every instant in this interval must be zero.
True
False
If a particle covers equal distances in equal time intervals, it is said to:
move with a uniform velocity
be at rest
move with a uniform speed
move with a uniform acceleration
Suppose a boy is enjoying a ride on a merry-go-round which is moving with a constant speed of 10 m/s. It means that the boy is:
At rest
Moving with no acceleration
In accelerated motion
Moving with uniform acceleration
Which of the following statement is correct regarding velocity and speed of a moving body?
Velocity of a moving body is always higher than its speed
Speed of a moving body is always higher than its velocity
Speed of a moving body is its velocity in a given direction
Velocity of a moving body is its speed in a given direction
When a car driver travelling at a speed of 10 m/s applies brakes and brings the car to rest in 20 s, then the retardation will be:
+ 2 m/s2
− 2 m/s2
− 0.5 m/s2
+ 0.5 m/s2
Which of the following is most likely a case of non-uniform circular motion?
Motion of the earth around the sun
Motion of a toy train on a circular track
Motion of a racing car on a circular track
Motion of hours’ hand on the dial of a clock
Which of the following is most likely a case of non-uniform circular motion?
Motion of the earth around the sun
Motion of a toy train on a circular track
Motion of a racing car on a circular track
Motion of hours’ hand on the dial of a clock
In a free fall, the velocity of a stone is increasing equally in equal intervals of time under the effect of gravitational force of the earth. Then what can you say about the motion of this stone? Whether the stone is having:
Uniform acceleration
Non-uniform acceleration
Retardation
Constant speed
