Does the acceleration of the object change while it is in flight?

Since the velocity of an object is composed of its speed and its direction, then an object under the influence of Earth's gravity will always be changing velocity.
If it is near the surface, its speed is slowing down if it is moving vertically up, or speeding up if it is moving vertically down. If it is moving horizontally, its speed is slowing because of air friction.
But even when it is in a circular orbit and its speed is not changing, the direction in which it is moving is constantly changing. so its velocity is constantly changing.
Since we have no information on what the flight is, there is no useful answer.

When you know both the speed and direction of an object's while it is in motion do you know the acceleration of the object?
No. For you to know acceleration you need the rate of change of speed and the direction.
How can an object be accelerating while traveling at the same speed?
Acceleration is the rate of change of VELOCITY, not of SPEED. If the velocity changes, there is acceleration. It is enough for the direction to change.
How is motion and acceleration alike And how are they different?
Motion is the measurement of an object and the change of its position over time. Acceleration is the measurement of velocity of an object. Both terms are used in physics. Acceleration denotes an increase of speed of an object while motion does not.
How is the gravitational force FG related to the distance between objects?
Fg is equal to mass times acceleration. While the mass of the object does not change, acceleration (gravity) increases the more the object falls to the ground.
What is the direction of the acceleration of an object that is slowing down while heading northward?
The acceleration is opposite the direction the object is moving, so the acceleration is negative and southward.

How do you know a moving object's acceleration?
Acceleration is the change in velocity. Velocity is the change in speed or direction. Therefore, acceleration is changing the change in speed or direction. So if you are going at 50mph and then you are going at 55mph and then at 60mph, your acceleration is constant at 5 mph. if the change in accleartion is changing, then it is not constant. If you turn dirctions even while you move at a constant velocity, you are accelerating.
What are the significant similarities and differences between velocity and acceleration?
The differences are that acceleration refers to the rate of change in velocity of an object while velocity is the rate of displacement of an object, and acceleration is measured in meters per squared seconds while velocity is measured in meters per second. On the other hand, they both use time as a component and they are both vectors in nature.
What happens to an object's acceleration as the size of the force acting on the object increases?
F=m.a , a=F/m; acceleration is directly proportional with force. acceleration increase while force increase.
An object with constant velocity has positive acceleration?
Answer This occurs when an object istraveling in one direction but has an acceleration in the opposite direction, which means it is decreasing in speed. For a given period of time, the speed has decreased. Acceleration is the change of velocity per second. T1 = 5 seconds V1 = 100mph T2 = 10 seconds V2= 50 mph Acceleration = (V2 - V1 ) / (T2 - T1) = (50-100)/(10-5) = -10 ft/sec/sec Positive(+) acceleration means an object will be going faster over an interval of time.
Is there a device that can change the weight of an object?
Since weight is a function of mass and acceleration, yes, it is called an elevator, whose acceleration as you ascend to the top of a building will, for a short while, change the acceleration factor of weight, thus increasing the weight of the object. Similarly, a rocket will first greatly increase the acceleration, but as it gets further away from the earth, and stops accelerating, the acceleration will drop below that of earths surface, which is 9.8 meters per second, per second. Changing the mass (typically what people think of when they think of weight.) of the object on the other hand, requires somehow changing the form of the object.
Which example describes constant acceleration due only to a change in direction?
In physics, acceleration is defined as a change in velocity. Velocity is the measurement of the rate (or speed) and direction of an object. Therefore, an object is "accelerating" when it changes direction while maintaining the same rate (or speed).
What would be the situation if mass were added to or lost from a system while a constant force was being applied to the system?
Since Force = Mass x Acceleration If force is held constant and one varies the mass then the acceleration will vary according to the equation: Acceleration = Force / Mass As a result, the acceleration is inversely proportional to the mass of the object. In other words, if one increases the mass of the object, the acceleration of the object will decrease proportionally. Similarly, if one decreases the mass of the object, the acceleration will increase proportionally.
