What is the definition of displacement?

• Displacement is the difference between the initial position and the final position.

• Displacement refers to the mass of an object in motion.
• Displacement is a scalar quantity that measures the speed of an object.
• Displacement is the total distance traveled by an object.

What is the definition of motion?

• Motion is the temperature change of an object.
• Motion is the force applied to an object.
• Motion is the process of changing position

• Motion is the speed of an object at rest.
