Physics 11 Dynamics X Mr. Jean

The plan: Video clip of the day Tomorrow’s force diagram questions Forces & Acceleration 2d forces

Force Diagram: Tomorrow: –You will be required to draw force diagrams for certain basic situations –Handed in for marks

Scoring System: 5 pts per diagram –2 pt proper diagram –2 pt proper forces & variables –1 pt proper assumptions Total of 4 situations

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 kg is accelerated from rest. Find the velocity of the electron if it experiences 5.8x N over a distance of m.

Draw the “Force Diagram”:

What is the acceleration?

Acceleration?
