Exploring Basic Physics Concepts

Which of the following is Newton's First Law of Motion?

• For every action, there is an equal and opposite reaction.

• An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

• The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

• The force of gravity acts between all masses.

Calculate the work done when a force of 10 N moves an object 5 meters in the direction of the force.
