system, not the Earth. Kepler develops the three laws of planetary motion. Galileo discovers that the natural state of an object is either at rest or moving with a constant speed, for as long as no unbalanced forces are acting on the object. Galileo reasons that if friction and other forces were balanced, an object would continue along at constant speed. Galileo understands the concept of acceleration and motion of objects acted upon by…

driving force is to push someone to a desired direction to cause change to take place. The driving force actualizes the patient to act in a desired manner and direction which is intended leading to a shift in the equilibrium to cause change. On the other hand, restraining forces counters the driving forces to hinder the change hence forcing the patient to reciprocate to an opposite direction. Restraining forces like driving forces, causes a shift in the equilibrium although this type of force…

is when external forces acting on a particle are balanced (zero resultant), the particle will be in equilibrium. But when external forces acting on a particle are not balanced, the particle will move in the direction of the resultant with magnitude ma. We use Newton’s second law to calculate the acceleration of a particle. Once the acceleration of a particle is known, we can apply equations of kinematics to obtain the…

track? Well I sure have, this is all due to centripetal force. This is a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving. The curves of these loops on rollercoasters resemble the curves of a circle. The coaster is continuously changing its direction while moving through the loop. This change in direction is caused by the presence of unbalanced forces and results in an acceleration. The acceleration of the…

duration of the vault and will stay in motion until an outside force acts upon them. After they reach the horse, they will stay in the air until that outside force acts upon them. That force is known as none other than gravity (-9.8 m/s2 ). Newton’s Second Law fits very close to the first law. It tells us that mass and acceleration are directly proportional in regards to force. This is known as the formula, F=(m)(a), which is force equals mass times acceleration. The more mass and acceleration…

time to calculate the acceleration, spring constant, and damping factor. The experiment was split into two different labs. Part one, the drop test, to take the block to a fixed height and drop it. This would then allow us to calculate the friction force, along with the acceleration of the metal block. Part two, the bounce test, is attaching the metal block to the spring, pushing the block down and releasing it. We would use these data to calculate the damping factor and the spring constant. To…

The acceleration of the object will increase as the force of the object increases. In this case the propelling force is thrust. In order to increase thrust, the water must be expelled from the rocket at a fast rate. Secondly as the mass decreases, acceleration will increase due to the inverse proportions and because of the increasing…

was not affected as much as the lighter weight objects (Frisbee and coffee filter) in terms of air drag. The outcomes of all experiments conducted were substantially correct, as they properly evaluated the consequences of objects in respect to drag force. As stated above, the first experiment, the acceleration of a falling mini-basketball, I had trouble visualizing the experiment and thus my predictions were incorrect with the final results. However, I soon realized that the position vs. time…

Y-Component x- X-Component Mathematical Model Basic Equations: Force Equation (used to find the force of any given object): F=ma F-Net Force, m-mass, a-acceleration Summation of Forces on X-Axis: 〖ΣF〗^x=F^(G,x)-F^Sp 〖ΣF〗^x is the sum of the forces on the x-axis, denoted by the superscript x, and the x-axis follows the Free-Body Diagram above. F^(G,x) is the x-component of the Force of Gravity by the Earth on the cart. F^Sp is the Force of Spring on the cart. Hooke’s Law for Springs:…
