That would be the gravitic force, or you could say 'the force of gravity'.
Gravitational force is what causes protostars to form. Gravity pulls together gas and dust in a molecular cloud, causing it to clump and collapse, eventually leading to the formation of a protostar.
The fundamental force that causes cohesion is the electromagnetic force. It is responsible for attracting and holding together atoms and molecules in a substance, allowing them to form stable structures. This force is mediated by the exchange of photons between charged particles.
The force that causes acceleration is known as net force.
Electricity is the force of what causes static cling in a dryer.
Because the rotation of the nebula creates an inward force to the center of the cloud.
The causes of force is the change of energy in space, f=dE/dr.
the force with which what the contract causes blood pressure
