Question

1. which statement is true about mass and inertia * 1 point

a. the greater the mass, the more inertia an object has
b. the small the mass, the slower it will go
c. the smaller the inertia, the more mass an object has
d. the greater the inertia, the greater the acceleration.

1. an object at rest will remain at rest and an object in motion will remain in * 1 point

motion, unless acted on by an unbalanced force. also called the law of
inertia. what law is this?
law 1
law 2
law 3

Explanation:

• Question 4:
• Inertia is the property of an object to resist changes in its state of motion. Mass is a measure of inertia. According to Newton's first law, the greater the mass of an object, the more it will resist changes in its motion (i.e., the more inertia it has).
• Option B: Mass does not directly determine how fast an object "goes" (velocity). Velocity is related to initial conditions and forces.
• Option C: Inertia and mass are directly proportional. A smaller inertia means a smaller mass.
• Option D: According to \(F = ma\) (Newton's second law), acceleration \(a=\frac{F}{m}\). For a given force \(F\), greater inertia (greater \(m\)) means smaller acceleration.
• Question 5:
• Newton's first law of motion states that an object at rest will remain at rest and an object in motion will remain in motion with a constant velocity (in a straight line) unless acted upon by an unbalanced force. This is also known as the law of inertia. Newton's second law is \(F = ma\) (relating force, mass, and acceleration), and Newton's third law is about action - reaction pairs (\(F_{action}=-F_{reaction}\)).

Answer:

• Question 4: A. The greater the mass, the more inertia an object has
• Question 5: Law 1
