... “I am in a state of motion” is not a valid statement. “My motion has changed” **is** a valid statement!! Reciprocity only applies to two inertial reference frames, one moving with respect to the other, that never change. The space traveler goes through multiple changes of reference frame (Earth, tri ...

Chapter 8 Section 3 Notes
... Newton’s Laws of Motion Newton’s First Law: An object at rest stays at rest and an object in motion stays in motion unless acted upon by an outside force. In other words, the net force acting on the object is zero. Example: A book sliding on any surface will eventually come to a stop due to fri ...

... Force is the same; acceleration depends on the mass; more mass is less acceleration according to Newton’s 2nd Law (F=ma) Coefficient of static friction: Increase incline until the box just starts to slip. Solve for the force of gravity parallel to the incline at that angle. This is equal to static f ...

Rotational Dynamics
... In analyzing the equilibrium of an object, we see that where a force is applied to an object influences the torque produced by the force. In particular, we sometimes need to know the location at which an object’s weight force acts on it. Think of the object as a collection of smaller pieces. ...

... The friction force is f = μkFn = (0.250)(18.9 N) = 4.73 N We choose up the incline as the positive x direction. The net force parallel to the incline while the block moves up the incline is ∑Fx = -mg sin(15.0) - f = -9.81 N The acceleration of the block is ax = ∑Fx / m = (-9.81 N) / (2.00 kg) = -4. ...
