Newton’s First law of motion is considered one of the most asked concept.
4 Questions around this concept.
Two block of masses
A block is kept on a frictionless inclined surface with an angle of inclination . The incline is given an acceleration to keep the block stationary. then a is equal to
Newton’s 1st law of motion states that if the (vector) sum of all the forces acting on a particle is zero, then and only then does the particle remain unaccelerated, i.e., remains at rest or moves with constant velocity.
If
Newton’s first law is also called the law of inertia.
Newton’s laws are valid in an inertial frame of reference but are not valid in a non-inertial frame of reference.
Frame of reference
A frame of reference is one in which the observer makes his observation.
Types of frame of reference:
Inertial frame of reference- A frame that is at rest or moving with uniform velocity along a
straight line.
Example- 1. Car moving with velocity v=constant
2. Lift at rest.
2. A non-inertial frame of reference- a frame that is accelerated and does not have a constant velocity.
Example- 1. The frame travels in a straight line but speeds up or slows down.
2. The frame travels along a curved path.
