Chapter 3: Forces and Newtons Laws of Motion

________ published his work, the Mathematical Principles of Natural Philosophy, in 1687, revolutionizing the rational study of mechanics by introducing mathematical principles that all of nature was considered to obey.

________ is a vector force that depends on an object's location in the universe, while mass is a scalar measure of an object's inertia.

A(n) ________ is required between that object and another object.

The ________ (g) is the same as the acceleration due to gravity in free fall and projectile motion.

________ are a visual tool used to represent the forces acting on an object.

The ability of an object to resist a change in its ________ is called inertia.

________ is the most common force and has its own formula.

cause no change in motion

cause an object to start moving, stop moving or change direction. The net force is greater than zero.

unbalanced forces

more inertia

Because of Newton's 3rd Law- action and reaction

the rate at which an object moves.

the rate at which velocity changes.

0 N

The attractive force that exists between all objects with mass

any physical object to any change in its state of motion including changes to its speed and direction or the state of rest

A force that opposes motion between two surfaces that are in contact
