Laws of motion with examples
Answers
Answer:
First law:Inertia
Newton's first law, also called the law of Inertia, states that an object remains at rest or continues in uniform motion unless it is compelled to change by the action of an external force. The object's tendency to remain at rest or maintain a constant speed is called Inertia and its resistance to deviation from Inertia varies with its mass. It takes physical effort - - a force--to overcome Inertia for a person to get out of bed in the morning. A bicycle or car will keep moving unless the rider or driver applies a Frictional force through the brakes to stop it. A driver or passenger in a moving car who is not wearing a seat belt will be thrown forward when the car suddenly stops because he remains in motion. Fastened the passenger's or driver's motion.
Second law :force and acceleration
Newton's second law defines the relationship between the change in the speed of a moving object - - it's acceleration - - -and the force acting upon it. This force equals the object's mass multiplied by its acceleration. It takes a smaller extra force to propel a small yacht at sea than to propel a super tanker because the latter has a greater mass than the former.
