The inertia of a moving object depends on
The force necessary to cause an acceleration of 1 m/s2 in an object of mass 1 kg is called .................. .
The ............... is proportional to the applied force and it occurs in the direction of the force.
What is acceleration?
v2 = u2 + 2as is the relation between ............... and ............. .
An object continues to remain at rest or in a state of uniform motion along a straight line unless an .............. acts on it.
One Newton is defined as the force which gives a mass of 1 kg and acceleration of............ .
If the velocity changes by equal amounts in equal time intervals, the object is said to be in ................. .
Which of the following does not belong with the others?
Rocket works on the principle of conservation of
Retardation means .............. acceleration.
Even if the displacement of an object is zero, the actual distance traversed by it...................
What is the numerical formula for force?
The tendency of a body to resist .................. acceleration is called .
According to Newton's first law of motion, an object will remain at rest or in uniform motion unless acted upon by:
The linear momentum of a system remains constant if no ............ force acts on it.
A body at rest explodes into two equal parts. Then, they move with
............... is an example of positive acceleration.
When a moving body comes to rest, then its initial velocity is taken as zero.
The unit of velocity in the SI system is .................... .
If a car is traveling at a constant speed around a curve, what is responsible for changing its direction?
What is the SI unit of momentum?
A student is able to move a block of mass 2 kg with minimum force of 1N. The force of friction between the object and the surface will be
Which of the following is an example of accelerated motion?
................... is the relation between displacement and time.
If an object is moving with a uniform velocity ........................ .
The displacement that occurs in unit time is called ................... .
Father has mass 60 kg and the mass of his son is 30 kg. The ratio of the inertia of the father to his child is
When body is performing uniform circular motion, its ................... changes at every point.
In a collision ................. is always conserved.
