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…

as how quickly and in what direction velocity changes. The equation for acceleration is: a=∆v/∆t in which the variable a represents acceleration, ∆v represents the change in velocity, and ∆t represents the time interval. In addition, gravity is the force that attracts a body towards any physical body that has mass. Galileo Galilei discovered that the distance a standard accelerating object travels is proportional to the square of the…

unbalanced force” In this video the athlete is at rest when he is first on the starting block. He is being acted upon by normal force between him and the block. When he bends down to pull with all his strength on the block he is creating a tension force between him and the block. He then gets power and pushes off the block with both feet. He is accelerating into the air and being acted upon by an unbalanced force. He is changing his motion and is no longer in constant motion.…

important. F=m(dv/dt)(Quote) F=ma Force = Mass x Acceleration (Newtons) With the use of this equation he proved that objects that are heavier fall at the same rate towards earth as objects that are lighter because the earth pulls them down with the same force. To put it in perspective a car and a feather would fall at the same universal rate of 9.8m/s^2 even though one is much heavier. Newton also figured out that the moon is held to the earth by the same force that pulls an apple off a tree…

Rube Goldberg Project For this Rube Goldberg project I am going to explain how my machine worked. My simple task was to pop a balloon. The item we used to pop the balloon was a mousetrap. I am going to go step by step through how I created my Rube Goldberg machine. First, we started out with a ramp that we dropped the ball on. That was our potential energy. Next, we had a ball drop down a tub at approximately 180°. That was mechanical energy. After that, the ball went through an elbow and…

novel Sula, Toni Morrison presents nature as an all controlling force over people in the Bottom by emphasizing the embodiment of nature in powerful characters, by depicting a sense of liberation in death, and by illustrating a lack of agency in the Bottom’s population. Morrison first suggests the pervasiveness of nature in the lives of people in the Bottom by creating parallels between powerful characters in the community and natural forces. With this humanized view of nature’s…

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…

Gravity is pushing down so much you're just weightless riding down a free fall. Then suddenly you're upside down going around 2 loops pass the gold mine express, where kinetic energy, In addition centripetal force, and terminal velocity is. Your flying past everything around the fastest corner gaining friction where little bushes and palm trees stand with anIn addition, you see giant boulders in the way surrounded by a stream.As acceleration speeds up you go…

Trajectory and applied force both have very much too do with our rocket lab. Trajectory affects how far the rocket will get beacuse trajectory is a curved path of an object that has been fired or thrown through the air. This affects the rocket beacuse the angle of the rocket that is launched at is part of trajectory and the rocket was launched off of an angled platform so this affetced how high the rocket went before coming down. Another part of trajectory is how gravity affects the objects…
