NEWTON’S 2 ND LAW OF MOTION By: Per.7
2
WHAT IS IT? Newton's second law Of Motion 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.
3
WHAT DOES IT MEAN? Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object). Heavier objects require more force to move a distance, as a lighter object requires less force to move the equal distance. Acceleration of an object depends on its mass and size and direction of the force acting on it.
4
The second law gives an exact relationship between force, mass, and acceleration. F=MxA Force = Mass times acceleration
5
DEFINITIONS Momentum - Characteristic of a moving body determined by the product of the body's mass and velocity. Mass - an object is related to the force required to accelerate it and hence is related to its inertia, and is essential to Newton's laws of motion. Velocity – The speed of something in a given direction.
