Inertia

Tendency of an object to resist a change in motion.

Proportional to an object’s mass:

Large mass High Inertia Difficult to move

Small mass Low Inertia Easy to move

Newton’s First Law of Motion

“Law of Inertia”

“Every object continues in a state of rest, or a state of motion in a straight line at constant speed, unless acted upon by an unbalanced force.”

Forces

Force: Push or pull (measured in Newtons [N])

Contact Forces: Forces that exist between surfaces that are touching

Field Forces: Forces that exist between surfaces that are not touching

“Free-Body” Diagrams

Example: A skydiver falling at constant velocity with an open parachute (ignore air resistance)

FT

v

a = 0 m/s2

Fg

Free – Body Diagrams

1. Object is drawn as a dot.

2. Force Vectors (): labeled and pointing in direction of force.

3. Arrows drawn starting from the dot, pointing away.

* 4. Draw acceleration and velocity vectors next to diagram.

Example: Free-body diagram of a
