Lesson 13 Moments – Turning forces
... • Dylan punches Henry in the face. If Henry’s head (mass 10 kg) was initially at rest and moves away from Dylans fist at 3 m/s, and the fist was in contact with the face for 0.2 seconds, what was the force of the punch? • m = 10kg, t = 0.2, u = 0, v = 3 • Ft = mv - mu ...

Presentation Lesson 09 Newton Second Law of Motion
... Usually called the law of inertia Every object continues in a state of rest, or of motion in a straight line at constant speed, unless it is compelled to change that state by an unbalanced force exerted upon it ...

... 1) Your instructor will demonstrate two toy cars moving up an incline. Explain the differences in the motion of the cars as they go up the incline. As the cars go up the incline, the car with metal wheels slips sooner than the car with rubber band wheels because there is more friction between the ru ...

... movement. Rigid frameworks, such as a bridge, a vehicle chassis, or the timber frame of a house or roof are examples of statics. If the forces acting on a system do not cancel each other, motion will result. The analysis of this kind of situation falls within the study of dynamics or of moving bodie ...
