TOPIC VI: Forces and Changes in Motion
ESSENTIAL CONTENT / Questions you can ask your child: /A. Motion can be described as a change in position of an object.
B. A change in motion:
1. Starting or stopping
2. Speeding up or
slowing down
3. Moving in a different
direction
C. Motion can be measured as speed or the change in position over a period of time.
1. Distance (meter stick)
2. Time (stopwatch)
D. Factors that determine motion.
1. Amount of force
2. Mass of the object
3. Change in speed
E. Familiar Forces
1. Pushes or Pulls
2. Gravity – force of attraction between objects that have mass
3. Magnetic attraction
4. Friction – Resistance to movement
F. Opposing forces act in opposite directions
G. Net force is a combination of all forces acting on an object
H. Balanced forces produce no change in motion of an object
1. Net force is zero.
I. Unbalanced forces produce a change in motion of an object
Net force is > zero. / / · What is motion? Give me some examples.
Sample answer: change in position of an object. For examples read letter B under essential content
· How can motion be measured?
Sample answer: Motion can be measured as speed or the change in position over a period of time.
· How can different forces change an object’s motion?
Sample answer: the following can speed up, slow down, start, stop, or cause the object to move in a different direction
ü Pushes or Pulls
ü Gravity – force of attraction between objects that have mass
ü Magnetic attraction
ü Friction – Resistance to movement
ü Opposing forces act in opposite directions
ü Net force is a combination of all forces acting on an object
ü Balanced forces produce no change in motion of an object
ü Unbalanced forces produce a change in motion of an object
