# What are all the equations of motion class 9?

## What are all the equations of motion class 9?

The following are the three equations of motion:

- First Equation of Motion : v = u + a t.
- Second Equation of Motion : s = u t + 1 2 a t 2.
- Third Equation of Motion : v 2 = u 2 + 2 a s.

**What is equation of motion class 9 definition?**

Equations of motion, in physics, are defined as equations that describe the behaviour of a physical system in terms of its motion as a function of time. There are three equations of motion that can be used to derive components such as displacement(s), velocity (initial and final), time(t) and acceleration(a).

**What is the 2nd equation of motion class 9?**

s = ut + ½ at². It is the expression gives the distance covered by the object moving with uniform acceleration.

### What are the 3 equations of motion class 9?

The three equations are,

- v = u + at.
- v² = u² + 2as.
- s = ut + ½at²

**What is the formula for motion?**

Newton’s second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass, F = ma, is the basic equation of motion in classical mechanics.

**What is the full form of physics?**

The full form of PHYSICS is. P=PHYSICAL. H=HEALTH. Y=YOUTHS. S=SCIENCE.

#### What is the R in physics?

universal gas constant, also called molar gas constant or gas constant, (symbol R), fundamental physical constant arising in the formulation of the ideal gas law.

**What are the 4 equations?**

They are often referred to as the SUVAT equations, where “SUVAT” is an acronym from the variables: s = displacement, u = initial velocity, v = final velocity, a = acceleration, t = time.

**What is uniform acceleration class9?**

Uniform acceleration: When an object is travelling in a straight line with an increase in velocity at equal intervals of time, then the object is said to be in uniform acceleration.

## What is the first equation of motion?

The first equation of motion is v = u +at. Here, v is the final velocity, u is the initial velocity, a is the acceleration and t is the time. The velocity-time relation gives the first equation of motion and can be used to find acceleration.
