What else can I help you with?
Is it possible to have positive acceleration?
Yes, it is possible to have positive acceleration if an object is speeding up in the direction of motion. Positive acceleration occurs when the velocity of an object is increasing, resulting in a change in speed or direction.
Does acceleration have a negative or positive value if the velocity is increasing speed?
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
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.
When is acceleration of an object positive?
Acceleration of an object is positive when its velocity is increasing over time. This means the object is speeding up in the direction of its motion.
What is the value of acceleration of an object in freefall?
If the object is falling close to earth the acceleration would be 9.81m/s^2. Be sure to define direction as positive or negative in the problem! (When I do problems I like to define the down direction as positive so I don't have to deal with too many negatives)
How does air resistance affect the acceleration of a falling object-How does air resistance affect the acceleration of a falling object?
It reduces the acceleration of the falling object due to friction.
What is the acceleration of a falling object?
The acceleration of a falling object is called gravity. A free-falling object has an acceleration of 9.8 m/s/s when going downward on Earth.
Is it possible for an object to have a constant acceleration and a non-zero velocity?
Yes, a falling apple meets that condition.
Is it possible to have positive acceleration?
Yes, it is possible to have positive acceleration if an object is speeding up in the direction of motion. Positive acceleration occurs when the velocity of an object is increasing, resulting in a change in speed or direction.
The acceleration of a falling object is cause by the force of?
Gravity
Does acceleration have a negative or positive value if the velocity is increasing speed?
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)

What happen to an object when it has positive acceleration?
Either of these is referred to as positive acceleration: A) the object's velocity is increasing in the frame of reference B) the object is being moved in a positive direction in a coordinate plane
When is acceleration of an object positive?
Acceleration of an object is positive when its velocity is increasing over time. This means the object is speeding up in the direction of its motion.
What is the acceleration of a falling object caused by?
Newton's Second Law of Acceleration says it is gravity.
What is the value of acceleration of an object in freefall?
If the object is falling close to earth the acceleration would be 9.81m/s^2. Be sure to define direction as positive or negative in the problem! (When I do problems I like to define the down direction as positive so I don't have to deal with too many negatives)
