Force and Motion -
... The negative sign of f means that its direction is the opposite of what we have guessed. One can also break down the forces along the tangential and radial directions to obtain the same answers. One can also take Earth as reference frame and introduce the inertia force to account for the rotational ...

Uniform Circular Motion
... direction.1 For the body to constantly change direction, rotate around an axis, and keep a constant speed the force must also be perpendicular to the direction of the velocity at all times.1 The forces direction must be towards the axis, essentially pulling the body inwards. As the velocity is alway ...

... Walk across the room and explain the difference between position (referred to a fixed origin), displacement (vector: measured from any position) and distance (scalar: total movement). Then move onto speed (the rate at which an object covers distance) and velocity (the rate of change of displacement) ...

Development of the Work Energy Concept in Mechanics
... First, the work done to displace the initial two meters, and then the work done to displace the final two meters. We have a constant force of 10 newtons with a displacement of 2 meters. The work done is Work = |10 n| |2m| cos 0 = 20 nm (or joules). We have a constant force of 5 newtons with a di ...

... A point mass is attached to the lower end of a light spring fixed at the upper end. The mass is made to oscillate vertically. If the potential energy of the system is taken to be zero when the mass is at its equilibrium position, the speed of the mass at the equilibrium position is directly proporti ...
