Important formulas for newton law of motion
Hello Daksh,
1. NEWTON'S FIRST LAW OF MOTION - this law does not have any specific formula.
2. NEWTON'S SECOND LAW OF MOTION -
Formula : F=maF = maF=ma
-
Where:
- F = net force (in newtons, N)
- m = mass (in kilograms, kg)
- a = acceleration (in meters per second squared, m/s²)
3. NEWTON'S THIRD LAW OF MOTION -
Principle : For every action, there is an equal and opposite reaction.
-
No specific formula, but it can be expressed as:
- F(action)= - F(reaction)
4. KINETIC EQUATION (FOR UNIFORMLY ACCELERATED BODY)
These equations are often used in conjunction with Newton's laws:
-
v=u+at
-
Where:
- v= final velocity
- u = initial velocity
- a = acceleration
- t = time
-
Where:
-
s=ut+(1/2)at2^s
-
Where:
- s = displacement
-
Where:
- v^2=u^2+2as
4. WEIGHT AND GRAVITATIONAL FORCE-
Formula : W=mgW = mgW=mg
-
Where:
- W = weight (in newtons, N)
- m = mass (in kilograms, kg)
- g = acceleration due to gravity
Here are the important formulas related to Newton's Laws of Motion in short:
-
Newton’s Second Law (Force and Acceleration) :
F=m⋅a- F = Force, m = Mass, a = Acceleration
-
Weight Formula :
W=m⋅g- W = Weight, m = Mass, g = Gravity (9.8 m/s^2)
-
Friction Force :
f=μ⋅N- f = Frictional Force, μ = Coefficient of Friction, N= Normal Force
-
Momentum :
p=m⋅v- p = Momentum, m = Mass, v = Velocity
Some formulas are very important in physics you have to learn before exam these are the most likely formula which came in boards or any exam frequently.
Force: F = ma, where force is equal to mass multiplied by acceleration
Momentum: p = mv, where momentum is equal to mass multiplied by velocity
Newton's first law: Fnet = 0 if velocity is constant
Newton's third law: FAB = -F
BA
