WorksheetsQuiz on Newton's Laws of Motion
Total questions: 25
Worksheet time: 13mins
Newton’s First Law mainly talks about:
Speed
Inertia
Heat
Light
According to Newton’s First Law, a body remains at rest or in uniform motion unless:
Time changes
External force acts on it
Mass increases
Temperature rises
Uniform motion means moving:
In a zig-zag path
In a straight line with constant speed
In circles only
With changing speed
The inability of a body to change its state of motion by itself is called:
Friction
Inertia
Pressure
Energy
The inability of a body to remain at rest is:
Inertia of direction
Inertia of motion
Inertia of rest
Momentum
The inability of a body to change its state of rest is:
Inertia of motion
Inertia of rest
Inertia of direction
Force
The inability of a body to change its direction of motion is:
Inertia of direction
Inertia of rest
Work
Power
Inertia of a body depends on its:
Colour
Mass
Shape
Temperature
Mass is a measure of:
Force
Inertia
Friction
Energy
A force may be defined as the physical cause that tends to:
Change the shape only
Change the state of a body
Increase temperature
Increase colour
Force can change:
Only temperature
Only mass
The state of motion
The colour of an object
If a body is at rest, a force can make it:
Remain at rest forever
Start moving
Lose mass
Glow
If a body is already moving, a force can:
Change its speed or direction
Stop all energy
Remove mass
Stop gravity
The total quantity of motion in a body is called:
Momentum
Inertia
Density
Force
Momentum of a body is equal to:
Mass × time
Mass × velocity
Force × speed
Mass ÷ volume
The symbol used for momentum is:
F
m
P
V
If mass increases, momentum:
Decreases
Increases
Becomes zero
Changes into inertia
If velocity becomes zero, momentum becomes:
Very large
Double
Zero
Constant
Momentum depends on:
Only mass
Only velocity
Both mass and velocity
Neither mass nor velocity
SI unit of momentum is:
kg m/s
m/s²
g cm/s
N/m
CGS unit of momentum is:
kg m/s
g cm/s
m/s²
g/s
Momentum becomes greater when:
Mass and velocity both are high
Mass is zero
Velocity is zero
Object is at rest
The velocity of a body in the momentum formula is denoted by:
P
V
m
F
The mass of a body in the momentum formula is denoted by:
F
t
m
P
If a body’s mass remains same but velocity increases, momentum:
Decreases
Remains same
Increases
Becomes zero
