What does the area under an acceleration time graph show?
The area under an acceleration-time graph is equal to the object's velocity (not change in velocity).
Is it possible for an object in freefall to have no acceleration?
No, but it is possible to not have an increase in speed. Because velocity is a directional quantity, not a scalar one, an object in freefall (by definition within a gravity field) is always under acceleration, just not necessarily one that alters its speed or even its position. Objects in orbit around a planet are in freefall (hence weightlessness) where the tangential component of their forward motion opposes the pull of gravity.
How is the acceleration of falling bodies determine experimentally?
For example, you can time how long it takes for an object to reach the floor. You also need to measure how far it falls down. If you assume constant acceleration, there is only one possible acceleration for any possible set of measurements.
Does pressure on an object affect its acceleration?
A submarine deep in the ocean is under great pressure, and a space capsule outside the atmosphere is under zero pressure. Both of them are capable of high acceleration, zero acceleration, and anything in between. The pressure is irrelevant.
What is An object acceleration only under the force of gravity is said to be in?
free fall.
The free fall acceleration of an object under earth's gravity is directed where?
The free fall acceleration of an object under Earth's gravity is directed downward, towards the center of the Earth. This acceleration is constant at approximately 9.81 m/s^2 on the surface of the Earth.
What are some common acceleration problems that students encounter in physics?
Some common acceleration problems that students encounter in physics include calculating the acceleration of an object given its initial and final velocities, determining the acceleration of an object moving along a curved path, and analyzing the acceleration of an object under the influence of friction or other external forces.
What is the formula for calculating the velocity of an object falling freely under gravity, considering the acceleration due to gravity as 2g?
The formula for calculating the velocity of an object falling freely under gravity, considering the acceleration due to gravity as 2g, is v (2gh), where v is the velocity, g is the acceleration due to gravity, and h is the height from which the object falls.
When an object changes speed does its acceleration change?
Yes, when an object changes speed, its acceleration changes. Acceleration is a measure of how quickly the speed of an object changes over time. So, if the speed changes, the acceleration of the object will also change.
What are some common acceleration problems in physics and how can they be solved?
Common acceleration problems in physics include calculating the acceleration of an object given its initial and final velocities, finding the acceleration of an object moving along a curved path, and determining the acceleration of an object under the influence of external forces like friction or gravity. These problems can be solved using equations of motion, Newton's laws of motion, and principles of kinematics. By analyzing the forces acting on the object and applying the appropriate formulas, one can determine the acceleration of the object in various scenarios.
How does acceleration change when object is thrown veritcally upward under ideal conditions?
From the time the object leaves your hand, its acceleration doesn't change at all ... it remains constant at 9.8 meters (32.2 feet) per second2 downward. Well, we have to admit that the acceleration does change to zero once the object hits the ground.
If an object is accelerating what equation relates the acceleration of that object the initial velocity and the final velocity and time?
Vf = Vi + at Where Vf = final velocity Vi = initial velocity a = acceleration t = time
