REVIEW ON PHYSICAL SCIENCE

How does mass affect an object's inertia?

• A. Mass has no effect on inertia
• B. Mass only affects objects at rest
• C. The greater the mass, the greater the inertia
• D. The smaller the mass, the greater the inertia

How does inertia explain why passengers lurch forward when a car abruptly stops?

• A. The passengers' bodies are pulled by gravity
• B. The passengers' bodies are attracted to the front of the car
• C. The passengers' bodies are pushed by the air inside the car
• D. The passengers' bodies resist the change to a state of rest due to their inertia

How does inertia affect objects at rest?

• A. Objects at rest have no inertia
• B. Objects at rest have infinite inertia
• C. Objects at rest will always be in motion
• D. Objects at rest will remain at rest unless acted upon by an external force

How does Newton's 1st law relate to an object in equilibrium?

• A. It experiences a constant acceleration.
• B. The net force on it is zero.
• C. It is always in motion.
• D. None

If an object is in equilibrium, which statement is true about its motion?

• A. It is at rest.
• B. It is accelerating.
• C. It is moving with a constant velocity.
• D. Both a and c.

Which of the following describes the relationship between mass and acceleration according to the Law of Acceleration?

• A. Opposite
• B. Not related.
• C. Directly proportional.
• D. Inversely proportional

If an object is in free fall near the surface of the Earth, what is the primary force acting on it, and how does it relate to the object's acceleration?

• A. Air resistance; inversely proportional to acceleration.
• B. Frictional force; directly proportional to acceleration.
• C. Gravitational force; directly proportional to acceleration.
• D. Gravitational force; inversely proportional to acceleration.

If two objects have the same force applied but different masses, how does their acceleration compare?

• A. Both objects have the same acceleration.
• B. The object with greater mass has greater acceleration.
• C. The object with smaller mass has greater acceleration.
• D. Acceleration cannot be determined without more information.
