How do you calculate the acceleration of gravity?
To calculate the acceleration of gravity, time (t) an object falling a certain distance (d) and the acceleration of gravity= d/t
How are spped velocity direction and acceleration the same?
acceleration=ratio of change in velocity in a specific direction to time. speed=ratio of distance to time.
What are some differences and similarities between acceleration and velocity?
Velocity is distance over time, Acceleration is velocity with a direction.
Acceleration is the change in distance over time True or false?
False. Acceleration is a change of speed or direction over time.
Compare and contrast speed and acceleration?
-- "Speed" is the rate at which distance changes. -- "Velocity" is speed along with the direction of motion. -- "Acceleration" is the rate at which velocity changes, including the direction of the change.
How do you calculate acceleration from distance and time?
Acceleration= Distance/time (distance divided by time) That's the dumbest answer I've ever heard.. Acceleration = Final Velocity - Initial Velocity/Time Velocity = Displacement/Time So you can't calculate acceleration from distance and time, you can only do velocity.

Is it true that to calculate acceleraltion you need to know both the final and the initial velocity of an object?
No. That's only one of several possibilities. -- with initial velocity, distance, and time, you can calculate acceleration -- with final velocity, distance, and time, you can calculate acceleration -- with force and mass, you can calculate acceleration -- with initial and final momentum, you can calculate acceleration -- with initial and final kinetic energy, you can calculate acceleration -- with mass, velocity at either end, and kinetic energy at the other end, you can calculate acceleration And I'm sure there are several more that I've missed.

Velocity is distance over time, Acceleration is velocity with a direction.
What is the difference between speed velocity acceleration?
Speed is the rate of change in distance, whereas velocity is speed and direction of travel. Acceleration is the change in velocity (including direction).
Acceleration is the change in distance over time True or false?
False. Acceleration is a change of speed or direction over time.
To find the acceleration of an object moving in a straight line you must calculate the charge in distance during unit of time?
You calculate the charge in velocity, not in distance.
Compare and contrast speed and acceleration?
-- "Speed" is the rate at which distance changes. -- "Velocity" is speed along with the direction of motion. -- "Acceleration" is the rate at which velocity changes, including the direction of the change.
How do you calculate acceleration when given velocity and distance?
v2 - u2 = 2as so that a = (v2 - u2)/2s where u = initial velocity v = final velocity s = distance a = acceleration
Why does a curve on a distance-time graph indicate acceleration?
The slope of a distance time graph is a measure of the rate of change in the distance of the object from a fixed reference point along the radial direction. If there were no acceleration in that direction then the radial velocity would be the same so that the graph would be a straight line. However, a curve indicates not only the the distance is changing with time, but that the rate of change is also changing. That is, the radial velocity is changing and that is indicative of radial acceleration.The word "radial" appear many times in the above paragraph. This is to emphasise that distance time graphs look only at the motion of an object in the direction towards or away from the reference point. Any motion is a transverse direction is ignored. Thus, a line with a constant gradient (slope) does not indicate that there is no acceleration but that any acceleration is in the direction at right angles to the reference direction.
How do you calculate measurement uncertainty for acceleration given uncertainty in time?
If the distance is known to perfection, an acceleration is constant, then the absolute error in the calculation of acceleration is 2/t3, where t is the measured time.
