Demonstrate the pull of gravity on two objects by placing a heavy ball onto the gravity well. What do we call a force that aligns with the direction of an object's motion? If the force applied aligns with the direction of the object's motion, we call it a pushing force: A pushing force is a force that aligns with the direction of the object's resulting state of motion. of power that we use. 60 seconds. The pull of gravity is a force that might set an object (or a skier) in motion. See answer (1) Copy. all objects in the universe attract each other through gravitational force. Q: The force that pulls objects towards each other is called? a. Poiseuille's equation does not hold if the flow velocity is high enough that turbulence sets in. We know that magnets are capable of attracting unlike poles and repelling like poles. There are four fundamental forces that can, depending on Apulling forceis a force in which an object moves towards the source of the interaction, either through direct contact or through the effect of a long-range force field. The stronger the pull of gravity on an object, the greater its weight.
