Force of Gravity

Who said that a force is necessary for an object to continue moving

• Aristotle

• Galileo

• Sir Isaac Newton

Who disputed Aristotle's claim by saying that it is natural for an object to remain at rest or to continue moving at a constant speed in a straight line

• Aristotle

• Galileo

• Sir Isaac Newton

Further developed Galileo's breakthrough by developing the three laws of motion

• Galileo

• Sir Isaac Newton

An object will remain at rest, or an object in motion will stay in motion unless acted upon by an unbalanced force

• Laws of force and acceleration

• law of inertia

• law of action-reaction

• forces of gravity

For every force, there is an opposite force. If the forces are balanced, an object will keep moving at the same speed
