What quantities must you measure to describe completely the motion of a ball tossed into the air?

What units are used to specify these quantities?

What are the three most commonly used systems of units?

What are the three fundamental mechanical quantities which form the basis for all mechanical measurement?

Describe how to add vectors graphically.

How do you resolve a vector into components?

How are the components used to accomplish vector addition?

How do you change components to polar form?

How is vector subtraction accomplished?

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.

Describe the motion of an object in free fall near the surface of the earth.

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?

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?

How are velocity and acceleration defined in terms of the vector displacement?

Show how relative velocities are combined to obtain a resultant velocity.
