• Newton's Second Law of Motion

• Newton's Third Law Motion

Which of the following always causes change in speed, direction, or both?

• balanced forces

• unbalanced forces

• either balanced or unbalanced forces

Newton's First Law of motion states that a moving object, unless it is acted on by an unbalanced force, will

• remain in motion

• eventually stop

• accelerate

The force of gravitational attraction between two objects depends on the distance between the objects and their

• masses

• shapes

• color
