Newton First Law MCQ (Multiple Choice Questions) PDF Download

Reference frame in which Newton's law holds is termed as

1. second reference frame
2. inertial reference frame
3. net reference frame
4. external reference frame

When two or more forces acts on a body, by adding the individual forces vectorially, we get

1. resultant force
2. initial force
3. origin force
4. kinetic force

Fact that states that a single force that has magnitude and direction of the net force has the same effect on the body as all the individual forces together is known as

1. principle of superposition for forces
2. principle of addition of forces
3. principle of initialization of forces
4. principle of superposition of velocities

A body will keep moving with a constant velocity, if

1. no force acts on it
2. external force acts on it
3. centripetal force acts on it
4. acceleration is variable

If no force acts on a body, the body's velocity cannot change, that is the body cannot accelerate, is the Newton's

1. 1st Law
2. 2nd Law
3. 3rd Law
4. 4th Law
