### Explain Newton’s second law of motion in your own words.

Newton’s second law of motion states that the force acting on an object is proportional to the rate of change of its momentum, and the change in momentum takes place in the direction of the force.

### Define the equation of force according to Newton’s second law of motion.

The equation of force according to Newton’s second law of motion is given by F = m * a, where F is the force, m is the mass of the object, and a is the acceleration.

### What are the initial and final momenta of a moving body?

The initial momentum of a moving body is given by P_i = mu, and the final momentum is given by P_f = mv.

### How is acceleration related to the change in velocity and time?

<p>Acceleration (a) is related to the change in velocity (v-u) and time (t) through the equation a = (v - u) / t.</p> Signup and view all the answers
