3.1 Define the term impulse in words. (2) 3.2 Calculate the magnitude of the momentum of each bullet when it leaves the gun. (3) 3.3 Calculate the average net force that each bullet exerts on the gun. (5) 3.4 Without any further calculation, write down the average net horizontal force that the mechanical support exerts on the gun. (2)
Non-conservative force A force for which the work done (in moving an object between two points) depends on the path taken. Examples are frictional force, air resistance, tension in a chord, etc.

Making an electric car for your Physics project for class 12th will set you apart from your classmates. It is easy to make and fascinating to see it work which makes it a perfect option for a project. The electric car works on a simple principle where the transmission of force from the motor to a wheel is carried through two gears and the use of ru...
Electric Motor is one of the most common and basic projects that you can think of. Though the concepts involved in the motor are complex making an electric motor is relatively easy. With just a requirement of a coil of wire, a magnet, and a power source, it is a preferred choice for your Physics Project for Class 12 if you have limited time. Materi...
Aim:The following experiment is conducted to check what happens to sound waves by creating a visual model of what happens when a vehicle passes by. Theory:The explanation for the Doppler effect is that each successive wave crest is produced from a position closer to the observer than the crest of the previous wave, as the source of the waves is hea...
Aim:The following experiment is to check and determine whether a rise in water density would cause a boat hull to sink deeper in the water to an observable degree as its temperature is elevated from 5 degrees C to 95 degrees C. Theory: This showed that increasing water temperature allows water molecules to move further out, decreasing upthrust in t...
Aim:How much of the electrical power supply of an incandescent lamp is lost by thermionic emission from the filament? If these damages are large, the operational performance of incandescent lamps could be substantially increased by their elimination. Theory:The power output can be decomposed into thermionic emission and thermal-radiation elements u...
Aim:The experiment is to equate straw insulation with traditional forms of insulation, which are fibreglass and rigid foam panels, which are widely used today. Theory: The most critical element in building an energy-effective contribution is adequate insulation. Insulation will hold the heat inside during cold days. Isolation will trap the sun outd...

A force is a push or pull that acts upon an object as a result of its interaction with other objects. Two Broad Categories of Forces: • Contact Forces: Normal Force, Tension Force, Friction Force, Spring Force, Air Resistance Force, Applied Force. • Field Forces: Gravity, electrical, magnetic.
Dec 16, 2023 · These forces determine which nuclei are stable and which decay, and they are the basis of the release of energy in certain nuclear reactions. Nuclear forces determine not only the stability of nuclei, but also the relative abundance of elements in nature.

A force is a push or pull that acts upon an object as a result of that objects interactions with its surroundings. In this Lesson, The Physics Classroom differentiates between the various types of forces that an object could encounter. Some extra attention is given to the topic of friction and weight.
