NEWTON'S LAWS OF MOTION by Rosanna Saprio https://padlet.com/r_saprio1/Lawsofmotion CLIL en-us 2017-10-03 15:11:16 UTC 2025-12-18 17:37:46 UTC hello@padlet.com r_saprio1 https://padlet.com/r_saprio1/Lawsofmotion/wish/193480422 Newton's laws of motion are three physical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces. More precisely, the first law defines the force qualitatively, the second law offers a quantitative measure of the force, and the third asserts that a single isolated force doesn't exist.]]> 2017-10-03 15:16:06 UTC https://padlet.com/r_saprio1/Lawsofmotion/wish/193480422 r_saprio1 https://padlet.com/r_saprio1/Lawsofmotion/wish/193480721
These three laws have been expressed in several different ways, over nearly three centuries, and can be summarised as follows:


First law: | In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force.
Second law: | In an inertial reference frame, the vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration a of the object: F = ma. (It is assumed here that the mass m is constant
Third law: | When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
