Chapter 5 Conceptual Physics Concept Summary

an object accelerates
when net force acts on it (speed and/or direction)
acceleration
directly proportional to net force acting on it
acceleration
inversely proportional to the mass of the object
acceleration
net force divided by mass
acceleration
same direction as net force
when object moves with constant velocity while an applied force acts on it
an equal and opposite force (friction) must also act to balance applied force
pressure
application of a force over an area
when force perpendicular to surface area
pressure equals force divided by area over which it acts
acceleration of all objects in free fall
is the same regardless of mass
when air resistance is present
falling object accelerates only until it reaches its terminal speed
at terminal speed
the force of air resistance balances force of gravity
