George JacksonPotential energy is stored in a compressed spring. How do you calculate spring compression in physics? F = -kx. The proportional constant k is called the spring constant. It is a measure of the spring’s stiffness. When a spring is stretched or compressed, so that its length changes by an amount x from its equilibrium … Read more
How do you graph speed and velocity? What is velocity Science Grade 7? Velocity defines the direction of the movement of the body or the object. Speed is primarily a scalar quantity. Velocity is essentially a vector quantity. It is the rate of change of distance. What is the relationship between acceleration and velocity vs … Read more
The ceiling fan has an electric AC motor that converts electrical energy into mechanical energy. How do you solve work and energy problems in physics? How do you solve work physics problems? Explanation: The formula for work is , work equals force times distance. In this case, there is only one force acting upon the … Read more
A fruit falling from the tree is a prominent example of free-fall motion. When the fruit gets ripened, it gets separated from the tree due to the action of the gravitational pull of the earth. The fruit separated from the tree then drops to the ground, displaying a free fall. What is a basic physics … Read more
Newton’s second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. What are the principles of Newton’s … Read more
5: The centripetal acceleration points toward the center of the circle. The tangential acceleration is tangential to the circle at the particle’s position. The total acceleration is the vector sum of the tangential and centripetal accelerations, which are perpendicular. How do you solve centripetal acceleration problems? What is the centripetal force exerted on a 1600 … Read more
Why are physics problems so hard? Why is Physics harder than Math? Answer: Physics demands problem-solving skills that can be developed only with practice. It also involves theoretical concepts, mathematical calculations and laboratory experiments that adds to the challenging concepts. What to do if you cant solve a physics problem? Answer. Go through the theory … Read more
For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters. Notice that gravitational potential energy has the same units as kinetic energy, kg m2 … Read more
Calculate the tension in the rope using the following equation: T = M x A. Four example, if you are trying to find T in a basic pulley system with an attached mass of 9g accelerating upwards at 2m/s² then T = 9g x 2m/s² = 18gm/s² or 18N (newtons). How do you solve pulley … Read more
Although any objects in motion through space are projectiles, they are commonly found in warfare and sports (for example, a thrown baseball, kicked football, fired bullet, shot arrow, stone released from catapult). How do you solve projectile motion problems in physics? What are 5 examples of projectile motion? Firing a Canon. Throwing a Basketball in … Read more
