 What is the unit of force? The newton, N What happens to a moving object if the resultant force on it is zero? It keeps moving What happens to a moving object if the resultant force on it is not zero? If the resultant force on an object is not zero it speeds up in the direction of the resultant force If we double the resultant force applied to an object, what happens to its acceleration? If we double the resultant force applied to an object its acceleration doubles What happens to a stationary object if the resultant force on it is zero?  It stays still In which direction does friction act? Friction acts in the opposite direction as the direction of movement Which force causes objects to fall? Weight, due to gravity, causes objects to fall When an object reaches terminal speed: The vertical forces on it are balanced On the Moon, if a hammer and feather were dropped together: Both objects hit the surface at the same time A parachutist on the Moon would never reach a terminal speed because: There is no air on the Moon AuthorCourtneyOsborn01 ID330844 Card SetP2 Revision DescriptionRevise!!!!!
