  1. 13) Hydrostatics Books. Hydrostatics is the branch of physics dedicated to the analysis of fluid equilibrium. It is the field of this science that focuses on researching phenomena related to fluids found in a container or vessel. To define what hydrostatics is, it is therefore essential to first refer to fluids.

  2. Figure 4.4 The force exerted by a stretched spring can be used as a standard unit of force. (a) This spring has a length x when undistorted. (b) When stretched a distance Δx , the spring exerts a restoring force, Frestore , which is reproducible. (c) A spring scale is one device that uses a spring to measure force.

  4. the motion of a body that is released at time t = 0 with an initial velocity ! 0. Two paths are shown in Figure 5.1. The dotted path represents a parabolic trajectory and the solid path represents the actual trajectory. The difference between the two paths ! v is a unit vector in the direction of the velocity.

  5. Step 1 - Sketch a motion diagram for an object that is moving at a constant velocity. An object with constant velocity travels the same distance in the same direction in each time interval. The motion diagram in Figure 2.9 shows equally spaced images along a straight line.

  6. Free Fall Case 3- object thrown upward. Initial velocity is upward, so it is toward positive y axis. The instantaneous velocity at the maximum height is zero Velocity and displacement are positive after time , t, from initial point. a = g everywhere in the motion and g = - 9.8 m/s2. g is always downward, negative.

  7. An impressed force is an action exerted upon a body, in order to change its state, either of rest, or of uniform motion in a right line.2. In order to define the magnitude of the force, he introduced a constant of proportionality, the inertial mass, which Newton called “quantity of matter”. Isaac Newton (1726).
