Forces II
... A reference frame in which an object with zero net force on it does not accelerate is known as an inertial reference frame. A reference frame attached to the Earth is a noninertial reference frame, since a net force is required to keep an object in one spot with respect to the reference frame. ...

• Introduction
... If body A exerts a force F AB (action) on body B, then body B exerts a force FBA (reaction) on A of the same intensity but in the opposite direction. In other words, for every action there is an equal and opposite reaction: FAB = - F BA The forces of action and reaction act on different bodies. Newt ...

Newton`s 3rd Law of Motion
... Newton’s 2nd Law describes quantitatively how forces affect motion. A force that is applied to any object is always applied by another object. Force on a nail is exerted by the hammer. But Newton realized that the hammer accelerated also. It came to a quick stop. Only a strong force could ca ...

Section 1 Newton`s Second Law
... 1. Weight decreases as an object moves away from Earth. 2. Weight results from a force; mass is a measure of how much matter an object contains. D. Objects in the space shuttle float because they have no force supporting them. E. Projectiles have horizontal and vertical velocities due to gravity, an ...

... 2nd Law • 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. In terms of ...

Force, Net Force, and Inertia
... • You may have heard the phrase, “An object in motion tends to stay in motion, and an object at rest will tend to stay at rest.” • In Physics we say, “A body moving at a constant velocity will stay at that velocity, and a body at rest will stay at rest, until an unbalanced force acts on that body.” ...
