  • What point is a bungee jumper’s greatest acceleration?

    The video asks students to predict when a bungee jumper experiences maximum acceleration. The answer is at the very bottom of the jump. This is often counter-intuitive as the velocity at this point is almost zero. As velocity is directional the maximum change occurs at the point the direction changes. What is the physics behind…

  • How do you calculate the force of a hydraulic jack?

    The amount of force a hydraulic cylinder can generate is equal to the hydraulic pressure times the effective area of the cylinder. (Effective Area is the surface area of the piston face in square inches.) FORMULAS: Force = psi x Area of Piston. How do you solve hydraulic lift problem? How does a hydraulic jack…

  • Do connected objects have the same acceleration?

    The magnitude of the acceleration will be the same for each object. How do you solve pulley problems in physics? How do you find the tension between two objects in physics? We know that the force of tension is calculated using the formula T = mg + ma. How do you find the contact force…

  • Why does classical physics fail to explain the photoelectric effect?

    This absence of lag time contradicts classical physics understanding, in which irradiated electrons would take a significant time to gain energy before they can leave the metal surface. What are some examples of photoelectric effect? Applications of the photoelectric effect brought us “electric eye” door openers, light meters used in photography, solar panels and photostatic…

  • What is the physics behind a parachute?

    When you first release the parachute, the force of gravity pulls it downward, and the parachute speeds toward the ground. The faster the parachute falls, though, the more drag it creates. The drag force resists the downward movement of gravity, pushing the parachute back up. What is the parachute problem? Introduction The “parachute problem” is…

  • What is the force of gravity acting on an object at 10000 meters above the earth’s surface?

    To calculate g force from velocity: Subtract initial velocity from final velocity. Divide the difference by time. Divide the resultant by the acceleration due to gravity, 9.81 m/s², to obtain the g force value. How do you solve gravitational force problems in physics? Is gravity 9.8 or 9.8 squared? Gravitational Force = (Gravitational Constant ×…

  • What is the difference between practical and conceptual problems?

    Conceptual physics is a laboratory science course with an emphasis on the scientific method and the fundamental principles of physics. This course is designed to provide students with a foundation for further study in biology, chemistry, and the advanced science courses. What does conceptual mean in physics? Physics concept questions or concept checking questions are…

  • What are the real life applications of derivatives?

    Application of Derivatives in Real Life To calculate the profit and loss in business using graphs. To check the temperature variation. To determine the speed or distance covered such as miles per hour, kilometre per hour etc. Derivatives are used to derive many equations in Physics. What is the application of derivative in physics? In…

  • What forces are used in shot put?

    The shot put consists of three movements: the glide or rotation, the standing power position, and the release. Movements involved in the hammer and discus include body rotation within the boundaries of a ring and rely on centripetal forces and torque, culminating with a release. How do you solve projectile motion problems in physics? How…

  • What are 5 examples of an inclined plane?

    Ramps. Stairs. Slides. Anthills. Slanted roofs. Escalators. How do you solve inclined problems in physics? What is the formula for an inclined plane? Sloping ramps, flyovers, roads on hills and staircases are a few examples of inclined planes. How do you solve a friction problem with an inclined plane? Inclined planes are simple machines used…

  • What are the physics of long jump?

    Their motion through the air is described by a parabola that is symmetric about its highest point. Once the jumper reaches this highest point they have zero velocity in the y-direction. Gravity then accelerates their motion back to the ground where they land a distance, R, from their take off point. How do you calculate…

  • How do you find the momentum of a bowling ball?

    How is physics used in bowling? The physics of bowling a strike dictates that to maximize the even distribution of force, the headpin should be struck at an angle of 30°. For bowling ball collisions and momentum, a hook ball technique is used. This technique contrasts the straight shot used by novices and for clearing…

  • What unit is force?

    The SI unit of force is the newton, symbol N. What is SI units PDF? SI units comprise a coherent system of units of measurement starting with seven base units, which are the second (the unit of time with the symbol s), meter (length, m), kilogram (mass, kg), ampere (electric current, A), kelvin (thermodynamic temperature,…

  • What is relative density PDF?

    Relative density. = mass of certain volume of substance (or material) / mass of an. equal volume of water. Note that for any substance/material. What is relative density in physics? Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given…

  • What is a final velocity?

    Initial velocity describes how fast an object travels when gravity first applies force on the object. On the other hand, the final velocity is a vector quantity that measures the speed and direction of a moving body after it has reached its maximum acceleration. What are the 5 kinematic formulas? v = v 0 +…
