gravity and mass
Two objects falling at the same time will fall with the same speed (assuming they both have similar shape and density)
Frontal surface area.
The two things that affect the gravitational force is Mass and Distance.
What are the two factors that affect an objects kinetic energy
What are the two factors that affect an objects kinetic energy
What are the two factors that affect an objects kinetic energy
The masses of the two objects and the distance between the two objects affect the gravitational force between them.
The mass of the object that is exerting the force and the distance between the two objects.
The masses of the objects and the distance between them
The coefficiant of friction between the two surfaces and the normal reaction force of the object lying on the surface
falling objects.
The object's velocity and cross sectional area.
