Use of force

is as rest it remains at rest or, if it is in motion, it moves with uniform velocity, until it is acted on by a resultant force. 2. Acceleration is dependent on the forces acting upon an object and the mass of the object. Therefore, if the force is increased, the acceleration is increased. And the more mass the object has, the more acceleration decreases. So the resultant force (F) is equal to mass (m) times acceleration (a) (F = ma). 3. For every action, there is an equal and opposite…

Introduction Variables exist in experiments and can be linked together in the form of an equation. Some equations have constants that link the variables together in a sort of relationship. Gravity is considered a constant in many formulae including equations of kinematics and projectiles. In this experiment, the simple pendulum apparatus can be used investigate the relationship between the time period and the length of the pendulum, with a constant value including the value of gravity. This is…

all the particles of a rigid body move along paths which are equidistant from fixed plane. 2 A force does work when it undergoes a displacement along its line of action. A force does work when it undergoes a displacement ds in the direction of the force. 3 Work and energy are scalar quantity For example : A force F does work on a particle when it undergoes a displacement in the direction of the force The displacement is dr = r’ – r The angle between tails of dr and F is θ and work dU…

Vertical dimension (VD) defined in the Glossary of Prosthodontic Terms as "The distance between two selected anatomic or marked points”. Occlusal vertical dimension (OVD) defined as "The distance between two selected anatomic points when in maximal inter-cuspal position”.(1) The OVD is determined by the repetitive contracted length of the elevator muscles which sets the jaw-to-jaw relationship.(2) During growth and development OVD affected by three factors: Growth of the ramus, gonial angle of…

all of the roller coasters without ever giving any thought to the physics behind the ride. There are several components of physics which contribute to the thrill of roller coasters, including gravitational forces, the law of conservation of energy, friction, centripetal force, and normal force, just to name a few. Gravity, the law of conservation of energy, and friction all play major roles in the functionality of roller coasters. A roller coaster ride typically begins with an ascent, powered…

INTRODUCTION • Energy is a scalar quantity. • It was first hypothesized by Newton to express kinetic and potential energies. • We cannot observe energy directly, but we can measure it using indirect methods and analyze its value. • Energy may be in different forms, such as potential, kinetic, magnetic or electrical. Potential energy of a system is by virtue of its location with respect to gravitational field. If an object has a mass m, located at elevation h, and acceleration due to gravity is g…

While designing any aerodynamic body an unspoken assumption of bilateral or mirror symmetry is taken into consideration. Argument against this bilateral symmetry states that “once the velocity of sound is exceeded, the laws of aerodynamics change in such a way as to make it seem inadvisable to arrange the components of an airplane side by side or abreast in a supersonic stream unless there are compelling reasons for such an arrangement.“ 2.1.1 Wave Drag This type of drag is formed as a result…

predetermined acceleration and velocity. The dynamic analysis is mainly used to determine the maximum torque needed during the mission; in order to select the DC-servomotors needed for each joint. Usually in case of complex manipulator it is suitable to use Lagrangian approach to get to do the dynamic analysis instead of Newton’s approach; which is done by calculating the position of the center of mass for each link including the end effectors as function of joint angles in the universal frame…

Stress: Stress is defined as ‘’the force across a boundary per unit area, for all orientations of that boundary.’’ It is derived from force, a physical quantity and area, a geometrical quantity. Therefore, stress is also characterized as a fundamental quantity, like velocity, energy, etc. that can be brought under quantification and can be analyzed without any obvious attention of the physical grounds of the material or of its nature. Example: When a solid bar is supporting a load, each…
