force, mass
Mass (gravity) & friction!
The two factors that describe motion are thing. :)
We generally think of kinetic energy as the energy of motion. And the two things that matter most as regards the energy of a moving object are its mass and its velocity.
What are the two factors that affect an objects kinetic energy
The two factors that affect an object's acceleration are the magnitude of the net force acting on the object and the object's mass. A larger net force or a smaller mass will result in a greater acceleration, according to Newton's second law of motion.
The object's speed and direction.
The two factors that affect the kinetic energy of an object are its mass and its velocity. The kinetic energy of an object increases with both mass and velocity.
The two factors that affect orbital motion are the mass of the objects involved and the distance between them. Gravitational force is stronger with larger masses and decreases as distance between objects increases.
force and speed
There are two factors that affect the gravitational attraction between two objects. The mass of each object and the distance between their centers of mass are the factors that affect the attraction.
The two factors that affect potential energy are the mass of the object and its height above the ground. As an object's mass or height increases, its potential energy also increases.
The mass and velocity of an object are two factors that affect its momentum. An object with higher mass or greater velocity will have greater momentum.
