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