Physics 11
Dynamics 16 – Dynamics to Kin III
Mr. Jean
The plan:
• Video clip of the day
• Forces & Acceleration
Combining Forces & Kinetics
• Understanding motion is really only
accomplished once you can see how the
forces interact with matter.
• Consider the following.
• Example: Old TV’s and computer monitors
produce pictures by firing electrons into a
screen. The viewers sees the electron as a
light change and this creates the resulting
image.
• TV Example: An electron with mass 9.1 x
10-31kg is accelerated from rest. Find the
velocity of the electron if it experiences
5.8x10-15 N over a distance of 0.0035m.
Draw the “Force Diagram”:
What is the acceleration?
