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.
No, the acceleration of an object in flight remains constant if there are no external forces acting on it. This is known as uniform acceleration.
If the only force on it is gravitational then a projectile's acceleration will remain constant until it hits the ground

Can a body have acceleration while at rest give example?
No, a body cannot have acceleration while at rest. Acceleration is the rate of change of an object's velocity, meaning it requires the object to be in motion. When an object is at rest, its velocity is zero, so there is no change in velocity, hence no acceleration.
How is motion and acceleration alike And how are they different?
Motion and acceleration are both concepts related to the movement of objects. Motion refers to the change in position of an object over time, while acceleration specifically refers to the rate of change in velocity of an object over time. In other words, acceleration is a measure of how the speed of an object is changing as it moves.
What is the difference between volicity and accleration?
Velocity is the rate of change of an object's position with respect to time, while acceleration is the rate of change of an object's velocity with respect to time. Essentially, velocity tells you how fast an object is moving and in what direction, while acceleration tells you how quickly an object is speeding up or slowing down.
How are velocity and acceleration different?
Velocity is the rate of change of position of an object with respect to time, while acceleration is the rate of change of velocity of an object with respect to time. Velocity describes how fast an object is moving and in which direction, while acceleration describes how quickly the velocity of an object is changing, either in speed or direction.
Is velocity the same as acceleration?
No, velocity and acceleration are not the same. Velocity is the rate of change of an object's position with respect to time, while acceleration is the rate of change of an object's velocity with respect to time. In other words, acceleration measures how quickly an object's velocity is changing.

How is speed and acceleration related?
Speed is a scalar quantity that represents the rate at which an object is moving, while acceleration is a vector quantity that represents the rate of change of an object's velocity. Acceleration can affect the speed of an object by either increasing or decreasing it, depending on whether the acceleration is in the same direction as the object's motion or in the opposite direction. In general, the greater the acceleration, the faster an object's speed will change.
Rate of change of velocity of a moving object?
The rate of change of velocity of a moving object is known as acceleration. Acceleration can be calculated by dividing the change in velocity by the time taken for the change to occur. Positive acceleration represents an increase in velocity, while negative acceleration (or deceleration) represents a decrease in velocity.
Are velocity and acceleration both rates of change?
Yes, velocity is the rate of change of an object's displacement over time, while acceleration is the rate of change of an object's velocity over time. Velocity indicates how fast an object's position changes, while acceleration describes how the velocity of an object changes over time.
Do acceleration and momentum mean the same thing?
No, acceleration and momentum are not the same. Acceleration refers to the rate of change of an object's velocity, while momentum is the product of an object's mass and velocity. Acceleration measures how quickly an object's velocity is changing, while momentum is a property that depends on both an object's mass and how fast it is moving.
How do you change centripetal acceleration?
Centripetal acceleration can be changed by altering the speed or direction of an object in circular motion. Increasing the speed will increase the centripetal acceleration, while changing the direction of motion will also change the centripetal acceleration.
How can you change an object's acceleration?
To change an object's acceleration, you can apply a force to the object in the direction you want to accelerate. Increasing the force will typically result in a higher acceleration, while decreasing the force will lead to a lower acceleration. Additionally, changing the mass of the object will also affect its acceleration, with a lighter object experiencing greater acceleration for the same force applied.
What do acceloration and velocity have in common?
Acceleration and velocity are both related to the motion of an object. Velocity is the rate of change of an object's position with respect to time, while acceleration is the rate of change of an object's velocity with respect to time. In other words, acceleration is the derivative of velocity with respect to time.
