Homework Statement
Why does an object with a bigger mass(more inertia) accelerate the same as an object with a lesser mass(less inertia) when in free fall?
I think I'm confused because an object with more inertia should resist it's change in state of motion morebrainpushups said:Well, what do you think?
the force of gravity is constant and causes a downward or negative acceleration.brainpushups said:Great. So what must that say about the force of gravity?
The force is constant for a given mass?, or are you saying it's the same for all masses?LeHotDoge said:the force of gravity is constant
Ermmm...a no would do. Remember Newton's law of universal gravitation explicitly indicates that distance between is crucial to the magnitude of the gravitational force two masses experience.LeHotDoge said:the force of gravity is constant and causes a downward or negative acceleration.
well the force of gravity is m*g , so a greater mass would have a greater force of gravity. Acceleration of an object is directly proportional to force(in this case force of gravity) and inversely proportional to mass, now I understand.haruspex said:The force is constant for a given mass?, or are you saying it's the same for all masses?
Inertia is the tendency of an object to resist changes in its state of motion, while gravity is the force of attraction between two objects due to their mass. In other words, inertia is a property of an object, while gravity is a force acting on that object.
Inertia causes an object to maintain its state of motion (either at rest or in motion) unless acted upon by an external force. Gravity, on the other hand, can cause an object to accelerate towards another object due to the force of attraction between them.
Yes, both inertia and gravity can be observed in everyday life. For example, when a car suddenly stops, passengers will continue to move forward due to their inertia. Gravity can also be observed when objects fall towards the ground or when planets orbit around the sun.
Inertia and gravity are related because an object's inertia is affected by its mass, and mass is also a factor in the force of gravity between objects. The more massive an object is, the greater its inertia and the stronger its gravitational pull.
Scientists study inertia and gravity through experiments and observations. They can also use mathematical equations, such as Newton's laws of motion and the law of universal gravitation, to understand and predict the behavior of objects under the influence of these forces.
