Question

What are the applications of Newton first law?

Answer 1

Answer:

Explanation:

here are plenty of applications to Newton's first law of motion. Consider a car moving west along a highway with a constant velocity of 65 miles per hour. What happens when the driver takes his foot off the gas pedal? According to Newton's first law of motion, the car should remain at a velocity of 65 mph, as long as the forces are balanced. As we have witnessed, however, the car slows down, and it comes to rest. This observation begs the question: what external forces act on the car to stop its motion?

The answer is friction. Friction is a force acting in the opposite direction of motion when two objects come into contact with each other. Without external forces, the car would continue to move west at 65 mph. Now, consider a golfer hitting a ball off the tee. While the ball is on the tee, it is said to be at rest. That is, it has no motion. Once the swinging club comes into contact with the ball, the club applies an external force, disrupts the state of balance and sends the ball flying into motion.

Answer 2

Explanation:

if a person stays in a same motion with the same speed and same direction unless acted upon the seat this is called Newton first law
