Hands on: How can you determine the average speed of an object rolling down an incline? How does the time to roll a sphere down an
incline depend on the height of the incline? If you double the height of the incline, does it cut the time in half?
If you know the acceleration of an object, how do you
find its speed and distance traveled at any given time?
(Assume straight-line motion, constant acceleration.)
Assuming constant acceleration, show a complete set
of motion equations which will describe any motion
meeting this condition.
A ball is thrown upward with a velocity of 30 m/s.
Find its height and velocity after 1 second. Find its
maximum height. Find its total time of flight when
it reaches its original height.
If you drop one ball and launch another horizontally
at the same time from the same height, will they
hit the ground at the same time?
If you fire a bullet horizontally and drop another
simultaneously, which will hit the ground first?
Describe the motion of an object in free fall near
the surface of the earth.
Relate the basic set of motion equations to trajectory
motion, neglecting air friction.
How can you predict whether the baseball is going
to clear the fence? What do you need to know?
