Topic:
Motion
An object’s motion can be described by it position,
direction of motion, and speed. The
motion of an object can be measured and represented on a graph. An object will remain at rest or continue to
move at a constant speed and direction unless an unbalanced force acts on it. When an unbalanced force acts on an object,
the change in speed or direction depends on the size and direction of the
force.
Technology Standards – 2, 3, 5, & 6
1. What is the equation
used to find the speed of an object?
2. How can you tell by looking at a speed
graph what object’s speed is
the fastest?
3. Describe the difference between distance
and displacement.
4. What is velocity and how is
it different from speed?
5. How do you calculate
velocity?
6. What is acceleration?
7. How does acceleration affect speed and
velocity?
8. What is the difference
between constant velocity and acceleration?
9. Can an object have both positive and
negative acceleration?
10. How does force
affect the movement of an object?
Follow up activity:
Make a motion story, that
shows the beginning and ending points of an object at zero, and shows the speed
of the object.
Make a position graph and
a distance graph from your story.
