What is the second law motion?
Newton’s second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables – the net force acting upon the object and the mass of the object.
What is Newton’s 2nd law of motion explain what it means in a sentence?
Newton’s second law of motion states that the change in linear momentum of a body is equal to the net impulse acting on it.
What is Newton second law of motion class 9?
Newton’s Second Law of Motion It states that the rate of change of momentum of a body is directly proportional to the applied force and takes place in the direction in which the force acts.
What does Newton’s second law states?
Newton’s second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.
How do you explain Newton’s second law of motion?
Newton’s second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force.
What is Newton’s second law in a sentence?
the rate of change of momentum is proportional to the imposed force and goes in the direction of the force.
What is second law of motion Short answer?
Newton’s second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. Newton’s second law is one of the most important in all of physics.
What were newtons exact words explaining second law of motion?
Newton’s Second Law of Motion states that If an external, unbalanced force is required to produce a change in velocity, then an external unbalanced force causes an acceleration. Or more simply put, force = mass x acceleration.
What are the three Newton laws of motion?
Along with Newton’s many discoveries, the three laws of motion are famous. These include inertia, acceleration, and the idea that for every action, there is an equal and opposite reaction. Inertia is the idea that a body in motion will remain in motion, and a body at rest will remain at rest.
What does newton second law of motion states?
Newton’s Second Law of Motion states that when a force acts on an object, it will cause the object to accelerate . The larger the mass of the object, the greater the force will need to be to cause it to accelerate.
What is formula expresses newton’s second law of motion?
Newton’s second law describes the affect of net force and mass upon the acceleration of an object. Often expressed as the equation a = Fnet/m (or rearranged to Fnet=m*a), the equation is probably the most important equation in all of Mechanics.
