According to the image, which of the following is a scalar quantity?

• Velocity

• Acceleration

• Mass

• Force

What does Newton's Third Law of Motion state as per the learning material in the image?

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

• The acceleration of an object depends on the mass of the object and the amount of force applied.

• An object at rest stays at rest, and an object in motion remains in motion at a constant speed and direction unless acted upon by an unbalanced force.

• The force of gravity acting on an object's mass.
