In a collision ................. is always conserved.
What is acceleration?
If a car is traveling at a constant speed around a curve, what is responsible for changing its direction?
Rocket works on the principle of conservation of
The displacement that occurs in unit time is called ................... .
................... is the relation between displacement and time.
The linear momentum of a system remains constant if no ............ force acts on it.
When body is performing uniform circular motion, its ................... changes at every point.
What is the SI unit of momentum?
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
The tendency of a body to resist .................. acceleration is called .
The inertia of a moving object depends on
............... is an example of positive acceleration.
Which of the following is an example of accelerated motion?
The unit of velocity in the SI system is .................... .
When a moving body comes to rest, then its initial velocity is taken as zero.
Retardation means .............. acceleration.
An object continues to remain at rest or in a state of uniform motion along a straight line unless an .............. acts on it.
A body at rest explodes into two equal parts. Then, they move with
The ............... is proportional to the applied force and it occurs in the direction of the force.
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?
According to Newton's first law of motion, an object will remain at rest or in uniform motion unless acted upon by:
v2 = u2 + 2as is the relation between ............... and ............. .
The force necessary to cause an acceleration of 1 m/s2 in an object of mass 1 kg is called .................. .
If an object is moving with a uniform velocity ........................ .
What is the numerical formula for force?
One Newton is defined as the force which gives a mass of 1 kg and acceleration of............ .
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
Even if the displacement of an object is zero, the actual distance traversed by it...................
