Use of force

longbow, the recurve bow, and the compound bow. Within these three different types of bows physics applies the same to all of these. In archery you take a bow and you knock an arrow to the string (connect the back of the arrow to the string), Then you use your…

also uses hamstrings, hip flexors, and calves. Certain exercises can make these muscles stronger for one’s vertical. Next, a vertical jump can also be determined by the fibers in the body. To have a higher vertical, one’s muscles need more fast twitch fibers. “They are better at generating short bursts of strength or speed than slow twitch fibers”(Quinn). Fast twitch fibers helps vertical jumping the most because for a vertical, one will need to burst into the air quickly with a lot of force.…

parachute, which can be proven through Newton’s second law, F=ma (Force=mass*acceleration). Rearranged, this gives a=F/m, where acceleration can also be gravity, if falling down. Another equation is a=v/t (acceleration=velocity/time) and a=(√2s)/t (acceleration=(sqrt2*distance)/time). The research question that this investigation will explore is: How is the drop time of a parachute affected by its mass? Photo 1: Parachute…

how planes are to be refuelled after a flight to be flown again, instead of building a new plane after every flight (The Verge, June 6th 2016). This waste on resources is more than enough reason to consider alternative systems, however continuing to use this expendable system will lead to drastic effects on space debris. According to NASA’s article on orbital space debris, there are currently more than 500,000 pieces of debris the size of marbles orbiting the Earth, travelling speeds nearing…

your body, trunk in an upright position, and use the muscles in the leg instead of the back (Early, 2013 pg 191).Proper body mechanics for the activity of tug of war, would be to stand in a staggered squat position, with one foot out while the other is lined up with the hip. Secondly, your trunk should be upright, even while pulling on the rope the trunk should remain in an upright position. Use your leg muscles to keep your stance, however you will use the muscles in your arm to pull the rope.…

character and properties of matter and energy. Matter of physics includes: mechanics, heat, light-weight and alternative radiation, sound, electricity, magnetism, and also the structure of atoms. Physics has many things that help us or things we use and we don't realise they include physics some of them are: Airbags in Cars, Bullets from Guns and Ultrasounds and X-rays. This experiment is an example of Newton’s Third Law of Motion: Action/Reaction. The experiment I will be conducting is…

an outside force,” this is applicable to when the gymnast is running toward the vault, as well as, when the gymnast is in the air. Gymnasts use their own force to propel themselves around the bar when performing the uneven bars event and will remain in motion unless acted upon by an outside force, and, in this case, the outside force would be gravity pulling the gymnast downward. Newton’s second law of motion states, “Mass and acceleration are directly proportional in regards to force,” or, “F =…

as well as dixie cups, a small plastic bag, and glue. As a machine can protect an egg breaking on the ground, so can machines protect rovers when landed on a planet. Through viewing this, you can find out what type of machine my partner and I will use for our very own egg drop, and where you would see it contrasted in daily life. Withal, how gravity affects it and how drag, air resistance, and cushioning may help our device in landing. Additionally, you’ll find out our initial plan and how we…

bulk friction of the assembly is usually too low compare to real material. There are two methods to increase the bulk friction which can be used separately or in combination. One method is to include contact rolling resistance and the other is to make use of non-spherical particles (Lu,…

work in space or any other sort of mediums. The first movement law is an object in motion will stay in motion unless acted upon by another force. The second law states, acceleration of an object is exerted by a net force is directly proportional to the magnitude of the net force. And the third law states, for every action there is an equal or unbalanced force. Around 400 BC a Greek named Archytas developed a wooden pigeon that could move through air. Escaping steam motivate the wires. However…
