All Flashcards
What is the effect of increasing the mass of two objects on the gravitational force between them?
Increasing the mass of either object will increase the gravitational force between them.
What happens to apparent weight when an elevator accelerates upwards?
Apparent weight increases; you feel heavier.
What happens to apparent weight when an elevator accelerates downwards?
Apparent weight decreases; you feel lighter.
What is the effect of being inside a uniform spherical shell of mass?
The net gravitational force on an object inside the shell is zero.
What is the effect of increasing the distance between two objects on the gravitational force between them?
Increasing the distance decreases the gravitational force between them, following an inverse square relationship.
What happens when an object is in freefall?
The object experiences weightlessness, with gravity being the only force acting on it.
What is the effect of increasing the mass of two objects on the gravitational force between them?
Increasing either mass increases the gravitational force proportionally.
What is the effect of increasing the distance between two objects on the gravitational force between them?
Increasing the distance decreases the gravitational force by the square of the distance.
What is the effect of upward acceleration on apparent weight?
Increased apparent weight.
What is the effect of downward acceleration on apparent weight?
Decreased apparent weight.
What is the effect of being in free fall?
Weightlessness.
What is the effect of an object having more inertial mass?
The object is harder to accelerate.
What is the effect of an object having more gravitational mass?
The object exerts a stronger gravitational pull.
What are the key differences between inertial and gravitational mass?
Inertial mass: Resistance to changes in motion | Gravitational mass: Relates to the force of gravitational attraction.
How does weight differ from apparent weight?
Weight: Gravitational force exerted on an object | Apparent weight: Magnitude of the normal force acting on an object.
