level questions: Level 1 of Circular Motion
| Question | Answer |
|---|---|
| Define linear velocity | Rate of change of linear displacement |
| Express linear velocity as all its equations | v = change in distance/ change in time v = rw v = (r2π)/T |
| Define angular velocity | Rate of change of angular displacement with respect to time |
| What are all the equations of angular velocity | w = change in angular displacement/ time w = linear speed/ radius w = 2πf w = 2π/T |
| Define angular displacement | Angle which correlates to the distance of circumference travelled |
| Give the equation for angular displacement | theta = s/r theta = 2π where s is distance of cirumfrance |
| Define centripetal force | Resultant perpendicular force toward the centre of circle required to keep a body in uniform motion |
| Give all the equations for centripetal force | F = mv^2/r F = mrw^2 F = mvw |
| How would you describe the direction of travel of centripetal force | Perpendicular to the direction of travel |
