what is newton law explain
Answers
Answer:
Newton's first law of motion:
if no force is acting on a body its velocity does not change my the body does not accelerate.in other words if a body is stationary it will remain stationary if it is in motion it will continue moving with the same velocity and in the same direction.
Answer:
1) Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it.
2) Force equals mass times acceleration [ ].
3) For every action there is an equal and opposite reaction.
Explanation:
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion.
For example,wearing a seat belt in a car while driving,if an accident occurs, or if brakes are applied to the car suddenly, the body will tend to continue its inertia and move forward, probably proving fatal.
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
For example,your bicycle is the mass. Your leg muscles pushing pushing on the pedals of your bicycle is the force.
Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.
