Projectile Motion The human body is no different to any other object, and must follow the laws of physics, and when jumping, Newton’s laws of motion…
Rotational period is the time it takes for that object to rotate just once. Rotational period is the term describing the length of time necessary for…
When running, there are four important external forces that definitely affect the kinetics of running: drag force, gravity, normal force, and friction. What are the 3 principles of running? These foundational principles in running are the pose, the fall, and the pull. The better you can do these 3 principles of running, the better runner…
You don’t have to be a mathematical genius to study physics, but you do need to know the basics, and college physics classes often use calculus and algebra. How is physics related to math? For physicists, math is a tool used to answer questions. For example, Newton invented calculus to help describe motion. For mathematicians,…
There are four (4) kinematic equations, which relate to displacement, D, velocity, v, time, t, and acceleration, a. Kinematic Equations Formula Questions. What are the four equations in physics? There are four basic kinematics equations: v = v 0 + a t. Î” x = ( v + v 0 2 ) t. Î” x…
The molecules present in the cell are made up of basic elements such as carbon, oxygen, hydrogen, and nitrogen. These elements possess energy; hence we can say that humans are made of energy. What are 5 examples of conservation of energy? A pendulum: As the pendulum swings down: A ball tossed up in the air:…
Induction is the process through which employees adjust or acclimatise to their new jobs and working environment. As part of this, ‘orientation’ can be used for a specific event that new starters attend, and ‘socialisation’ can describe the way in which new employees build working relationships within their new teams. What is a real life…
Electricity is the movement of electrons. Electrons create charge, which we can harness to do work. Your lightbulb, your stereo, your phone, etc., are all harnessing the movement of the electrons in order to do work. They all operate using the same basic power source: the movement of electrons. What is the role of physics…
One end of the strings is supported on bridges, which are attached to the soundboard. The vibrations of the strings are transmitted to the soundboard through the bridges, and a loud sound resonates as a result of the soundboard vibrating the air. The entire piano, notably the soundboard, vibrates to produce sound. What waves do…
There are three primary flight control laws – Normal Law, Alternate Law and Direct Law. How do Newton’s laws apply to flight? A: Newton’s second law states that Force equals mass times acceleration, or F=ma. This means that the force needed to accelerate an airplane in any direction is equal to the mass of the…
The particle model is a scientific theory that explains the properties of solids, liquids and gases by suggesting that all matter is made of particles, and that those particles behave differently in solids, liquids and gases. A diagram showing the particle model for solids, liquids and gases. What is the particle model simple? Simple particle…
Objects in space follow the laws or rules of physics, just like objects on Earth do. Things in space have inertia. That is, they travel in a straight line unless there is a force that makes them stop or change. The movement of things in space is influenced by gravity. How do spaceships accelerate in…
The acceleration on any surface is the measure of the force exerted by the surface. The friction force, which is supposed to stop the motion, is eliminated on the frictionless surface. Since the net forces act on the body become zero, acceleration in frictionless surfaces is also zero. What is the formula for the acceleration…
The quality of physics teaching is to be developed considerably so as to achieve its purposes and objectives to understand basic principles, to develop problem solving analytical skills and ability to apply them. The physics teaching must be effective and innovative and beneficial to pupils. What are the problems in teaching physics? Other problems which…
This feeling is caused by the change in direction of the roller coaster. At the top of a roller coaster, the car goes from moving upward to flat to moving downward. This change in direction is known as acceleration and the acceleration makes riders feel as if a force is acting on them, pulling them…
One of the most important numbers in our universe is the number Pi or Ï€. Explore humankind’s odysseyâ€”attempts throughout the ages that truly transcend culturesâ€”to compute, approximate, and understand this enigmatic number. What is the most difficult physics question? 1. What is matter made of? We know matter is made up atoms, and atoms are…
Formula. D = m / (FW – IW) Initial Water Level (mL) Final Water level (mL) Mass (g) What is displacement of water in physics? When an object enters water, it pushes out water to make room for itself. The object pushes out a volume of water that is equal to its own volume. This…
Four forces act on the boat: its weight, the buoyant force (the contact force with the water that pushes the boat up), the forward force of the wind, and the backward drag of the water. How is boating explain the Newton’s third law? The force of wind on the sail causing the boat to move…
In particular, shock waves travel faster than sound, and their speed increases as the amplitude is raised; but the intensity of a shock wave also decreases faster than does that of a sound wave, because some of the energy of the shock wave is expended to heat the medium in which it travels. What is…
Why does a rotating wheel not fall? The reason the bike wheel does not fall flat when it is spinning is because, like all moving objects, it has momentum. To distinguish the momentum due to the spinning of an object, it is called angular momentum â€“ a concept students first encounter in senior physics. How…
Vector Tug of War: If several forces are acting on an object say F1, F2 and F3, then the resultant force on the object is given by Resultant Force = F1 + F2 + F3. Some notable examples: 1. If an object is at rest (not moving), then the sum of the forces must be…
Because of the mathematical principle that any three points must always lie in the same plane, whereas this is not necessarily true for four points. Is a 3-legged table more stable? Three legs are always more stable.” This assumption is correct, as a tripod is always stable on uneven ground. However, there are a few…
