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.
What are the key differences between inertial mass and gravitational mass?
Inertial mass: Resistance to acceleration (F=ma) | Gravitational mass: Determines gravitational force (F = G(m1m2)/r^2). Experimentally, they are the same.
How does apparent weight differ from actual weight?
Actual weight: Gravitational force on an object. | Apparent weight: The force you feel, influenced by acceleration (normal force).
Compare and contrast gravitational force and gravitational field.
Gravitational Force: the force of attraction between two masses. | Gravitational Field: The influence zone around a massive object.
Differentiate between the effects of upward and downward acceleration on apparent weight.
Upward Acceleration: Apparent weight > true weight | Downward Acceleration: Apparent weight < true weight
Define Newton's Law of Universal Gravitation.
The gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers of mass: F = G rac{m_1 m_2}{r^2}
What is gravitational field strength ()?
Gravitational field strength is the gravitational force per unit mass: g = rac{F}{m}
Define weight in the context of gravitational force.
Weight is the gravitational force exerted by a large astronomical body on a smaller nearby object:
What is apparent weight?
Apparent weight is the magnitude of the normal force acting on an object. It's what you feel as weight.
Define inertial mass.
Inertial mass measures an object's resistance to changes in motion when interacting with another object.
What is gravitational mass?
Gravitational mass relates to the force of attraction between two objects with mass.
