Physics Motion and Free Fall Equations

In summary, Distance is the total length traveled by an object, while displacement is the change in position from the starting point to the ending point. Velocity is a vector quantity that describes the rate of change of an object's position, including its direction. Speed, on the other hand, is a scalar quantity that only describes the rate of change of an object's position, regardless of direction. The acceleration due to gravity on Earth is approximately 9.8 m/s^2, and air resistance can significantly affect an object's free fall. However, an object can only experience true free fall in a uniform gravitational field.

I am just looking for--or perhaps one of u could just post them--a list of physics motion equations in 1d, and freefall

u know v=x/t v(f)=v(i)... v(f)2=v(i)2...etc


thx

I am happy to provide you with a list of commonly used physics motion equations in 1D and free fall. These equations are essential in understanding the behavior of objects in motion and can be applied to a wide range of situations.

1D Motion Equations:

1. Average velocity (v) = change in position (Δx) / change in time (Δt)
2. Final velocity (v) = initial velocity (v0) + acceleration (a) * time (t)
3. Displacement (x) = initial velocity (v0) * time (t) + 1/2 * acceleration (a) * time (t)^2
4. Final velocity (v) = initial velocity (v0) + 1/2 * acceleration (a) * time (t)
5. Final velocity (v) = √(initial velocity (v0)^2 + 2 * acceleration (a) * displacement (x))
6. Acceleration (a) = (final velocity (v) - initial velocity (v0)) / time (t)
7. Average acceleration (a) = change in velocity (Δv) / change in time (Δt)

Free Fall Equations:

1. Final velocity (vf) = initial velocity (v0) + acceleration due to gravity (g) * time (t)
2. Displacement (y) = initial velocity (v0) * time (t) + 1/2 * acceleration due to gravity (g) * time (t)^2
3. Final velocity (vf) = initial velocity (v0) + 1/2 * acceleration due to gravity (g) * time (t)
4. Final velocity (vf) = √(initial velocity (v0)^2 + 2 * acceleration due to gravity (g) * displacement (y))
5. Acceleration due to gravity (g) = (final velocity (vf) - initial velocity (v0)) / time (t)
6. Average acceleration due to gravity (g) = change in velocity (Δv) / change in time (Δt)

I hope this list of equations is helpful to you. It is important to note that these equations are just a few examples and there are many more that can be used in different scenarios. It is also crucial to understand the underlying principles and assumptions behind these equations to apply
 

1. What is the difference between distance and displacement?

Distance is the total length traveled by an object, while displacement is the change in position from the starting point to the ending point. Distance is a scalar quantity, while displacement is a vector quantity.

2. How does velocity differ from speed?

Velocity is a vector quantity that describes the rate of change of an object's position, including its direction. Speed, on the other hand, is a scalar quantity that only describes the rate of change of an object's position, regardless of direction.

3. What is the acceleration due to gravity on Earth?

The acceleration due to gravity on Earth is approximately 9.8 m/s^2, which means that an object in free fall near the surface of the Earth will accelerate at a rate of 9.8 meters per second, per second.

4. How does air resistance affect free fall?

Air resistance, also known as drag, is a force that opposes the motion of an object through air. It can significantly impact the acceleration and velocity of an object in free fall, slowing it down as it falls. The amount of air resistance depends on the shape and size of the object, as well as the density of the air.

5. Can an object experience free fall on a non-uniform gravitational field?

No, an object can only experience true free fall in a uniform gravitational field, where the acceleration due to gravity is constant. In a non-uniform gravitational field, the acceleration and velocity of an object will vary, preventing it from experiencing true free fall.
