Chapter 2: Motion in One Dimension

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.

How are instantaneous velocity and acceleration defined in terms of derivatives?

Given a position as a function of time, how do you find the acceleration?

Given acceleration as a function of time, how do you find the position?

For an object with constant acceleration, show that integration of the acceleration leads to the motion equations for velocity and position.

Homework set#2

*Motion equations

*Motion calculation

*Motion explorer

*Vertical trajectory

*Free fall

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?
