7.1 ROTATIONAL MOTION
A car is driving at a constant speed of 13.6 m/s (about 30 mph), moving counter-clockwise on a circular track as shown. yes yes
a) Is this car accelerating? ____________
b) If the car suddenly lost all traction and started skidding exactly when it is at the location, sketch which direction will it skid (if the driver does nothing).
Change in velocity as time goes by
Change in velocity as time goes by
Review Acceleration:
Magnitude or direction (not units) Direction only
Magnitude or direction (not units) Direction only
Acceleration means _______________________________________________ What CAN change for a velocity vector? _____________________________________ What IS changing when something moves in a circle? ____________________________
an object in motion continues in constant-velocity motion in a straight line an object in motion continues in constant-velocity motion in a straight line
Review Newton’s 1st Law:
An object at rest remains at rest, OR ____________________________________________ _________________________________________________________________________ UNLESS the object experiences a net or unbalanced external force.
Example 1: The car accelerates at locations
