3) Newton`s 2nd law
4) Newton`s 3rd law
5) Force
Answers
Answer:
Momentum can be well defined as the measure of the kinetic energy of the object. In simple words, the momentum is the product of mass and velocity
In the first law, we come to understand that an object will not change its motion unless a force acts on it.
The second law states that the force on an object is equal to its mass times its acceleration.
And, finally, the third law states that for every action, there is an equal and opposite reaction.
A force involves an interaction between two or more objects, and it causes a push or pull between the objects. .
Answer:
momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction
Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
Newton's Second Law of Motion says that acceleration (gaining speed) happens when a force acts on a mass
Newton's third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction.
A force is any influence that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate.
