Answer 1

Answer:

Force and momentum

Explanation:

Answer 2

Answer:

⇒ The second law of motion gives the measure of Force.

Explanation :

➳ As per newton's second law of motion, Force is defined as the rate of change of linear momentum.

Mathematically,

$\bigstar\:\boxed{\bf{F=\dfrac{dP}{dt}}}$

• F denotes force
• dP denotes change in momentum
• dt denotes change in time

➳ Momentum is defined as the product of mass and velocity. P = mv

$\bigstar\:\boxed{\bf{F=\dfrac{m(v-u)}{dt}}}$

• m denotes mass
• v denotes final velocity
• u denotes initial velocity
• t denotes time

➳ In other words, Force is defined the product of mass and acceleration because acceleration is defined as the rate of change of velocity.

$\bigstar\:\boxed{\bf{F=ma}}$

⟶ SI unit of Force : N

⟶ Force is a polar vector quantity.
