Question

1. what are the natural states of motion? list all correct answers.

a. being stopped
b. moving with constant direction
c. moving with changing speed
d. moving with constant velocity

Explanation:

Step1: Recall Newton's first law

Newton's first law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Step2: Analyze each option

• Option a: Being stopped (at rest) is a natural state as per Newton's first law if no un - balanced force acts.
• Option b: Moving with constant direction (and if we assume constant speed, which is implied in the context of natural motion as per Newton's first law when no un - balanced force acts) is a natural state.
• Option c: Moving with constant speed (and if we assume constant direction, which is implied in the context of natural motion as per Newton's first law when no un - balanced force acts) is a natural state.
• Option d: Moving with changing velocity means there is an acceleration. According to Newton's first law, if there is an acceleration, there must be an un - balanced force acting on the object. So, it is not a natural state.

Answer:

a. Being stopped, b. Moving with constant direction, c. Moving with constant speed
