What is true about objects falling due to gravity?
When gravity pulls objects toward the ground, it always causes them to accelerate at a rate of 9.8 m/s2. Regardless of differences in mass, all objects accelerate at the same rate due to gravity unless air resistance affects one more than another.
Does gravity cause things to fall?
The answer is gravity: an invisible force that pulls objects toward each other. Earth’s gravity is what keeps you on the ground and what makes things fall. Objects with more mass have more gravity. Gravity also gets weaker with distance.
Why does gravity make things fall at the same time?
The heavier object takes more force to accelerate but gravity exerts more force on it since there is more mass to act on. The lighter object takes less force to accelerate but gravity exerts less force on it since there is less mass. The result is that it balances out so they have the same acceleration.
Which one of the following statement for an object falling freely under the influence of gravity is correct?
Detailed Solution. The correct answer is Acceleration is constant all throughout the free fall. An object that is moving only because of the action of gravity is said to be free-falling and its motion is described by Newton’s second law of motion.
How does gravity hold us to the ground and make objects fall?
The universal law of gravitation says that gravity pulls toward the centers of objects, which in this case means the ball falls in the direction of the center of the Earth. In other words, it falls downward, since “down” is always toward the center of the Earth. Why does the ball accelerate, getting faster as it falls?
Why do things fall at the same time?
As such, all objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth’s surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity.
What is it called when the force of gravity is acting on an object?
The mass of an object refers to the amount of matter that is contained by the object; the weight of an object is the force of gravity acting upon that object.
How does gravity affect the passage of time?
Gravity slows the passage of time. Similar to how the passage of time is changed under special relativity, general relativity predicts that massive objects will also dilate time. The more massive the object, the more noticeable the effect.
Is gravity actually curved space?
If gravity is actually curved space and if falling objects are simply following the natural curves of space why does each object have its own curve? This is a great question which goes to the heart of why Einstein said gravity is the curvature of space-time, rather than just the curvature of space.
How do mass and weight affect free fall acceleration?
The more massive an object, the faster its acceleration of gravity. Heavier objects will free-fall more quickly than lighter objects. Objects in free-fall do not experience air resistance. Mass and weight are the same. Objects in free-fall do not experience air resistance. A baseball is dropped off the side of a cliff.
What is gravity according to Albert Einstein?
It is here that Einstein connected the dots to suggest that gravity is the warping of space and time. Gravity is the curvature of the universe, caused by massive bodies, which determines the path that objects travel. That curvature is dynamical, moving as those objects move.
