Fire is the physical representation of the oxidation of material which releases heat, light and other products. Oxidation is exothermic and thus releases the chemical energy in the bonds of the burning material. Heat causes this release and breakdown of chemical bonds.
From the magnet.
Photons do not exert force on each other, as they are massless particles that carry electromagnetic force. Neutrinos also do not exert force on each other, as they only interact weakly through the weak nuclear force and gravity.
Yes
no they don't
Your feet exert a force on the ground so in return the ground exerts a force on your feet.
The objects with bigger masses exert more pulling force. However, even though all the matter around us exert a force, their masses are too small for them to exert a 'feelable' force. But yes, they do exert a force, but its negligible.
The force you exert towards yourself is called self-force or self-interaction force.
The force you exert on a sponge when you squeeze it is called compression force.
The force that you exert on a lever can be called the effort force. The lever has three parts. They are: the fulcrum, the load, and the effort force. This can also be classified as the input force. The force that you exert to perform a task is known as the input force.
do you exert more force when you are further from the fulcrum
You exert force when you pull on anything.
They exert Gravitational Force on each other. It is a force which is directly proportional to Mass of the object
The amount of force you exert remains the same, but the distance over which you exert the force can affect the work done. If you exert a force over a longer distance, you may do more work because the force acts over a greater distance. If the distance over which you exert the force is shorter, the work done may be less.
Both, you exert a force onto the sidewalk, and the sidewalk "pushes back" with an equal, but opposite force.
When you exert a force on an object, it exerts an equal and opposite force on you, as described by Newton's third law of motion. This means for every action force, there is a reaction force of equal magnitude in the opposite direction.
Machines make work easier by: -Changing the amount of force you exert -Changing the distance in which you exert your force -Changing the direction in which you exert your force
Effort Force.
