... Momentum is moving inertia. We can rewrite Newton’s 1st law to include momentum. “An object that is moving will continue to move in the direction the force was applied until another force is applied” The greater the momentum the greater the force required to stop it e.g. small /large snowball. Momen ...

... where you were pushing the door. The force you used was 50N, at a distance 1.0m from the pivot point. You hit the door perpendicular to its plane, so the angle between the door and the direction of force was 90 degrees. Since = r x F = r F sin( ) then the torque on the door was: = (1.0m) (50N) sin(9 ...
