Goal: To explain the concept of relative motion and the difference between an object’s velocity and its acceleration.
Objectives:
Students will be able to:
- explain the idea that motion is relative.
- define speed and give examples of units for speed.
- distinguish between instantaneous speed and average speed.
- distinguish between speed and velocity.
- describe how to tell whether a velocity is changing.
- define acceleration and give examples of units for acceleration.
- describe the motion of an object in free fall from rest.
- describe the motion on an object thrown straight up until it hits the ground, when air resistance is negligible.
- determine the speed and the distance fallen at any time after an object dropped from rest, when air resistance is negligible.
- explain why acceleration is a rate of a rate.
- construct a graph of the distance and velocity vs time for a moving object.
-use kinematic equations of motion to calculate and describe various aspects of motion.
