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
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.
