Normal force

revolves around the force and coefficients of friction. Static friction is the force that prevents a stationary object from moving. The direction of static friction is opposite to applied force. Kinetic friction is the force that acts against an object’s motion. The direction of kinetic friction is opposite to the object’s velocity. Frictional forces act parallel to the surfaces they act upon. The coefficient of kinetic and static friction both show the magnitude. Between the forces and the materials

81m/s2) the Normal and Frictional Force were calculate. With the use of this experiment some conclusions have been drawn. For instance the main result is that the friction increases if one of the following variables increases: the weight of the box, the size of the box and the weight that is being pulled. Although there are some other factors that affect the friction but they have not been tested in this experiment. For example the surface that the box is places on affects the frictional force that is

10/04/2017 Abstract: The main objective of this lab was to measure the friction force it takes to start moving a weighted block across a table, and as it continued to move. This force was tested experimentally in three separate ways. The force was then solved graphically and mathematically through six different runs per method. TALK ABOUT RESULTS HERE. Theory: Friction is the force that opposes the force applied on an object, as well as the motion of the object. The two types of friction

8.0 Discussion 8.1 Analysis of Results By analysing the data obtained from the experiment, two main trends were identified. Excluding surface B (desk), the first trend observed showed that the amount of static frictional force resisting the motion of the wooden block was substantially greater when the object was placed on a rough surface, as opposed to when it was placed on a smooth surface. This is understood through the numerical data compiled in Table 7.1, which indicates that surface A (tiles)

climber has fallen off the wall and is hanging by the rope. In the sport of rock climbing, the goal is, obviously enough, to reach the top. In other words, the challenge is ultimately to surmount the force of gravity. The power to do this is generated by the climber’s muscles, but friction forces also play a key role in making the ascent up a rock face. These

no exception to the physical laws of Mother Nature. Friction is a resistive force that always acts in a direction that is opposite to the motion of a body. Frictional forces are dependent on two components; the coefficient of friction and the normal force. Friction = (µ)(n) There are two different types of frictional coefficients, static and kinetic. The coefficient of static friction is the frictional force that must be overcome before any motion commences. It is caused by the minuscule

It is normal for these shearers to have up to 1 megawatt of power! Blasting is used in mining to break up rock or create space. Explosives are placed in a blasting hole and then detonated. The velocity of the detonation of the explosives are enormous. The

will continue at a constant velocity (speed or direction) unless acted upon a net external force. A force is considered a push or a pull acting on an object (given in units of Newtons (N)). There are two types of forces: a contact force, which two objects are in direct contact, and field force, which is when two objects exert a push or a pull but are separated by distance. For this discussion contact forces will be the focus; contact between the skater and the board and contact with the board and

What forces are responsible for the movement of ocean water in currents? What forces and factors influence the which direction and how strong ocean currents are? Forces are responsible for the movement of ocean water is wind, sun heat, gravity and the density of the water. The forces and factor influence the direction and how strong the ocean are gravity, Coriolis Effect also the the shape of the ocean basins. What is a gyre? How many large gyres exist in the world ocean? Where are they located
