An electron gun fires electrons into a magnetic field directed straight downward. Find the direction of the force exerted by the field on an electron for each of the following directions of the electron’s velocity: (a) horizontal and due north; (b) horizontal and 30° west of north; (c) due north‚ but at 30° below the horizontal; (d) straight upward. 2. (a) Find the direction of the force on a proton moving through the magnetic fields in Figure 1‚ as shown. (b) Repeat part (a)‚ assuming the moving

gravitation. The English physicist Isaac Newton (1642-1727) introduced the term "gravity" after he saw an apple falling onto the ground in his garden. "Gravity" is the force of attraction exerted by the earth on an object. The moon orbits around the earth because of gravity too. Newton later proposed that gravity was just a particular case of gravitation. Every mass in the universe attracts every other mass. This is the main idea of Newton’s Law of Universal Gravitation.

Centripetal force (from Latin centrum "center" and petere "to seek"[1]) is a force that makes a body follow a curved path: its direction is always orthogonal to the velocity of the body‚ toward the fixed point of the instantaneous center of curvature of the path. Centripetal force is generally the cause of circular motion. In simple terms‚ centripetal force is defined as a force which keeps a body moving with a uniform speed along a circular path and is directed along the radius towards the centre

Centrifugal force Centrifugal force (from Latin centrum‚ meaning "center"‚ and fugere‚ meaning "to flee") is the apparent outward force that draws a rotating body away from the center of rotation. It is caused by the inertia of the body as the body’s path is continually redirected. In Newtonian mechanics‚ the term centrifugal force is used to refer to one of two distinct concepts: an inertial force (also called a "fictitious" force) observed in a non-inertial reference frame‚ and a reaction force corresponding

INTRODUCTION For this experiment we studied an oxidation-reduction reaction of magnesium and hydrochloric acid solution. We compared the experimental measured amount of a product and the amount predicted by the theoretical calculation of a balanced equation: Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g) PROCEDURE First we obtained a strip of pre-cut magnesium ribbon‚ cleaned it with steel wool to remove any signs of oxidation from the strip (which would alter our results)‚ and then weighed it (individual

The Use of Force The Wichita Police Department’s policy and procedures on the use of force for its employees takes every measure of precautionary to ensure that the best method of force is used in making a lawful arrest. These policies and procedures go into great detail to inform officers when the use of force is necessary and how much force is needed. An officer of the WPD is justified in using force as long as they believe it to be necessary to effect the arrest and to defend one’s self or another
