Question

write 3 equations of motion​

Answer 1

★ First equation of motion ★

→ v = u + at.

• v = final velocity.
• u = initial velocity.
• a = acceleration.
• t = time taken.

Note :- first equation of motion also called velocity time equation.

★ Second equation of motion ★

→ s = ut + ½ at².

• u = initial velocity.
• a = acceleration.
• t = time taken.
• s = distance covered.

Note :- second equation of motion also called positive time equation.

★ Third equation of motion ★

→ v² - u² = 2as

• v = final velocity.
• u = initial velocity.
• a = acceleration.

Note :- third equation of motion also called velocity positive equation.

_____________________________

★ First law of motion ★

→ first law of motion states that an object continues to be in a state of rest or of uniform motion along a straight line unless acted upon by an unbalanced force.

★ Second law of motion ★

→ second law of motion states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force.

★ Third law of motion ★

→ third law of motion states that for every action there is an equal and opposite reaction and they act on two different bodies.

Answer 2

Answer:

✡ First we have to understand what is equation of motion:-

✏ Equation of motion are motion that describe the behaviour of a physical system in terms of its motion as a function of time.

✡ Now there are three Equation of motion:-

⬛) First Equation of motion:-

✴ v = u + at ✴

⬛) Second Equation of motion:-

✴ v² = u² + 2as ✴

⬛) Third Equation of motion:-

✴ s = ut + $\dfrac{1}{2}$at²

( where,

• s = displacement;
• u = intial velocity;
• v = final velocity;
• a = acceleration
• t = time of motion

Note:- These equation are reffered as SUVAT equation where SUVAT stands for

• s = displacement
• u = initial velocity
• v = final velocity
• a = acceleration
• t = time
