Force and Translational Dynamics
Imagine you are in a spaceship far from any gravitational influences, accelerating at . According to the equivalence principle, what would you observe?
You would float weightlessly inside the spaceship.
You would feel a force pressing you towards the front of the spaceship.
You would feel a force pressing you towards the back of the spaceship, similar to gravity on Earth.
You would experience time dilation.

Which of the following statements correctly distinguishes between mass and weight?
Mass is a force, while weight is a measure of inertia.
Mass is a measure of the amount of matter in an object, while weight is the gravitational force on that object.
Mass and weight are the same thing, just measured in different units.
Weight is a scalar quantity, while mass is a vector quantity.
What are the units of gravitational field strength ()?
N
