Weight is not anything but the force which an object experiences due to gravity. The Energy spent to do work in a unit amount of time is termed as Power. The capacity to do some work is termed as Energy. The density of material shows the denseness of it in a specific given area.Īccording to Newton’s second law of motion, the force can be expressed by the product of mass and acceleration of the body. The average speed is the average of speed of a moving body for the overall distance that it has covered.Īcceleration is defined as the rate of change in velocity to the change in time. Some basic but very important Physics formula is given below: 1) Average Speed Formula: Here we will have some basic physics formula with examples. With these, we have to use our ability and creativity and good sort of potential to find solutions. During applications, we may come across many concepts, problems, and mathematical formulas. Work is equal to the force times the distance and is measured in joules.Physics is all about articulating the things with real values and not memorizing them up. Work - Work occurs in physics when a force acts on an object to move it some distance. In physics, weight is measured in newtons. Weight - Weight is the force of gravity on an object. Watt - The watt is the standard unit of measure for power. The magnitude of velocity is the object's speed. Velocity - Velocity is the rate of change in an object's position. Vector - A vector is a quantity that has both a magnitude and a direction. Third law of motion - The third law of motion states that for every action there is an equal and opposite reaction. It is a scalar quantity measured by distance over time. Speed - Speed is the measurement of how fast on object moves relative to a reference point. Some examples of simple machines include the lever, pulley, inclined plane, wedge, and screw. Simple machine - A simple machine is a basic mechanical device for applying a force and doing work. Second law of motion - The second law of motion states that the greater the mass of an object, the more force it will take to accelerate the object. Unlike a vector, a scalar does not have direction. Scalar - A scalar is a measurement that only measures the magnitude. Pressure - Pressure is the force over a given area. Power is calculated by dividing work over time. Power - Power is a measurement of the rate at which energy is used. Potential energy - Potential energy is the energy stored by an object due to its state or position. Pascal - The pascal is the standard unit of measure for pressure. Newton - The newton is the standard unit of measure for force. It is a vector measured in newton-seconds. Momentum is equal to the mass times the velocity of an object. Momentum - Momentum is a measurement of mass in motion. Mass - Mass is a measurement of how much matter is in an object.
It is a scalar quantity calculated using the formula KE = ½ * m * v 2, where m = mass and v = velocity. Kinetic energy - Kinetic energy is the energy an object has due to its motion. Joule - The joule is the standard unit of measure for energy and work. Impulse - An impulse is a change in momentum. On Earth gravity pulls at objects with an acceleration of 9.8 m/s 2. Gravity - Gravity is a force caused when the mass of physical bodies attract each other. It is a force and is measured in newtons. Force is a vector measured in newtons.įriction - Friction is the resistance of motion when one object rubs against another. The standard unit of measure for energy is the joule.įirst law of motion - The first law of motion states that any object in motion will continue to move in the same direction and speed unless external forces act on it.įorce - Force is the measurement of a push or pull on an object. It is a vector quantity.Įnergy - Energy is the ability to do work. Acceleration is a vector.Ĭollision - A collision in physics occurs when any two objects bump into each other.ĭisplacement - In physics, displacement refers to an object's overall change in position. It is equal to the change in velocity over the change in time. Acceleration - Acceleration is the measurement of the change in an object's velocity.
