1. The following events related to untochable force: (1) coconuts falling from the tree to the ground (2) Attract magnetic iron plates (3) footwear be worn after long use (4) Budi push the beam to shift to the right The above events involving untouchable force is the number of events .... a. 1 and 2 b. 1 and 3 c. 2 and 4 d. 4 2. Amir and Badu are playing tug of war. Amir pull to the left with a force of 200 N while Badu pull to the right by the force of 350 N. resultant force generated is ....…

1. The pendulum of a clock swings back and forth. At what position will its kinetic energy be the greatest? At what position will its kinetic energy equal its potential energy? When the pendulum of a clock swings back and forth, the pendulum reaches its maximum potential energy at the top of the swing, and it reaches its maximum kinetic energy at the bottom of the swing. In the absence of frictional forces, the pendulum’s kinetic energy will be equal to its potential energy at the bottom of the…

the weight starts to drop the gravitational potential energy begins to decrease while the spring’s potential energy increases as it begins to stretch. During the middle the kinetic energy is at its maximum since the kinetic energy is the energy of motion. Lastly, as the weight nears the ground, the gravitational potential energy is at its minimum since the weight is as close as possible to the ground, the springs potential energy reaches its maximum since the spring is as stretched as it will go…

Our Rube Goldberg machine used several physics concepts in order to complete its simple task, which was to turn on a Roomba. One of the most prominent physics concepts within our project was gravity and/or gravitational potential energy, which could be seen in places such as the inclined planes and the hammer swinging down. Gravity was the downward-pulling force that allowed the energy to be transferred from the top level, to the Roomba on the floor. The toppling rule was another major concept…

Grant Alexander Pd#6 11 November 2016 Trebuchet Engineering A trebuchet is a machine used in medieval siege warfare for hurling large stones or other missiles. How this machine works is not to complex but is also fascinating. The object that is being shot is held in the sling, which is on a launch trough whose job is to make sure the shot is straight. Also the trough is there to prevent the sling getting caught in the framework of the trebuchet. When putting the arm of the trebuchet down,…

scientists and mathematicians as a parabola, and objects that fly in the shape of a parabola are said to be in parabolic motion. A projectiles motion can be broken up into two separate pieces, horizontal and vertical motion. These two motions act independently of each other meaning no matter how much one of them changes the other will be unaffected. While in parabolic motion the only motion…

will investigate relationship between force, mass, and the motion of objects. 2. How does your rubber band car show Newton’s 1st Law of Motion? The first law states an object will stay at rest until acted upon unbalanced force. The car is at rest until the rubber band is twirl all on the stick. This mean a force has to be added for the rubber-band car to move. 3. How does your rubber band car show Newton’s 2nd Law of Motion? The second law is Force X Mass= Acceleration. The force is the…

The purpose of the experiment was to determine how altering the amount of mass in a makeshift rocket will affect its distance. Our hypothesis stated that when more mass is added to the rocket, its distance will also increase. To investigate this theory, we conducted an experiment in which the mass of the rocket would be changed using differentiating amounts of water. To measure the height of the bottle rocket, we took rope and attached it to the girth of the liter bottle to determine how high…

his laws, Therefore, making Newton sad. One example is that in the video there are ships flying. However, because there is no air in space, there is no air resistance, meaning there is nothing pushing against the ships so that they could fly. In Newton’s first law, he states that “Every body perseveres in its state of rest, or uniform of motion in a right line, unless it is compelled to change that state by forces impresses thereon” It is the law of inertia. This scene goes against this law…

The foot and ground exert an equal and opposite force on each other. This is known as the ground reaction force.12 The position and acceleration of the runner's center of mass regulates the direction and magnitude of the ground reaction force. For instance, a runner sprinting from a standstill. Throughout the initial phase of acceleration, the body is inclined forward and therefore the center of gravity falls in front of the contact surface. After many gait cycles, the runner reaches top speed…
