Answer 1

Answer:

1) Rate of change in momentum is equal to Force

2) Distance covered by the car is measured by odometer

3) Above formula is used to measure the Gravitational force between two masses

Explanation:

1)

As per Newton's 2nd law we know that rate of change in momentum is equal to the net force acting on the system

so we will have

$F = \frac{dP}{dt}$

2)

Distance covered by the car is measured by the

Odometer

3)

As we know that the gravitational force between two objects is measured by the formula

$F = \frac{Gm_1m_2}{r^2}$
