Examples of Newton's 2nd law of motion?

Answer 1

Newton's second law states that an object will change acceleration if pushed or pulled upon. An example would be pushing a ball, the velocity goes from 0 to how hard you push the ball. Newton's second law also states that if it gets twice the mass it accelerates half as much. An example would be pushing a 10 lb ball as hard as you can, then pushing a 5 lb ball as hard as you can. The 10 lb ball would accelerate less than the 5 lb ball because the 10 lb ball has more mass.

Newton's second law is related to unbalanced forces. Hence they should be a net force for application of Newton's Second Law of Motion. If you push a ball then it will not move initially due to the force of friction. Once you push harder and your force is more than the force of friction then the ball will start moving. The amount of acceleration of the ball is related by F = ma. Hence more mass means less acceleration. Similarly more force means more acceleration.

Answer 2

There are three Newton's law of motion namely: First Law of Motion, Second Law of Motion, and Third Law of Motion. A Rugby ball will not move until it is kicked is an example of the First law of motion.

Answer 3

well the way newtons second law is stated is kinda hard to comprehend sometimes if you're in the beginning of physics

lets say in a perfect universe, without friction or gravity


you push something like ball, it will not accelerate or decelerate.


so lets say you push a ball with a velocity of 4m/sec it will stay moving at 4m/sec forever unless you stop with something else.


now in real life. there is a lot of variables that affect newtons second law


like gravity, and friction are one of the two biggest.


and another thing stated by the law
something will stand completely still.
lets say you put a ball in space but don't touch it all
it won't move at all until you move it.


hope that helps

Answer 4

A rocket. The hot gases rushing out of a rockets bottom exerts a force opposite to the direction of the gases and this acts on the rocket. You can duplicate this easily at home by filling a balloon with air and leave it keeping its mouth open. The balloon will travel upwards fotr a few feet.

Answer 5

1. When a force is applied to a soccer ball, it accelerates according to the equation F = ma.
2. The acceleration of a car is directly proportional to the force applied by the engine and inversely proportional to its mass, as described by Newton's second law.
3. When a person pushes a shopping cart, the acceleration of the cart depends on both the force exerted by the person and the mass of the cart, in accordance with Newton's second law of motion.

Answer 6

Weighing yourself on a scale, weight=mg or Newtons F=ma, weight = Force F and g = acceleration a.

Answer 7

Newton's second law of motion states that acceleration depends on the net force acting on an object and on the object's mass.
