Motion
A car moved 60 km East and 90 km West. What is the distance?
150km
What is the equation to calculate force?
Force = Mass * Acceleration
What is the equation to calculate centripetal force?
Centripetal Force = (Mass * Velocity^2) / Radius
Average velocity can be calculated by dividing displacement over what?

4N
A mass attached to a string that is itself attached to the ceiling swings back and forth. Where will the acceleration, and thus force, be the greatest?
At the lowest point.
