What else can I help you with?
A vertically launched object When is the acceleration due to gravity greater when ascending from the top or descending?
As long as the object stays somewhere near the surface of the earth, the acceleration due to gravity is constant, whether the object is moving up, down, sideways, or not moving at all.
What happens to the acceleration due to gravity of an object in projectile?
The acceleration due to gravity of an object in projectile motion remains constant throughout its motion. Gravity acts vertically downward and causes the object to accelerate at a rate of approximately 9.81 m/s^2.
What is a fired thrown or otherwise propelled object?
A projectile is a fired, thrown, or otherwise propelled object that is intended to hit a target. Examples of projectiles include bullets, arrows, and cannonballs.
Give a situation when an object is with 0 velocitybut wieh a constant accelaration?
If you through an object up, at its highest point it will have zero velocity (only for that instant). But all the time it is subject to an acceleration of 9.8 meters per square second (downward).
Why does the speed dcreses when an object is thrown vertically up?
The speed decreases when an object is thrown vertically up because of the force of gravity acting against the object's upward motion. As the object goes higher, the force of gravity slows it down until the object reaches its maximum height, where its speed momentarily becomes zero before accelerating back downward.
How is air resistance is force?
It requires a force to propel an object through air, because of the air resistance. Normally, if there were no air resistance and the object were being propelled on the level with no friction, a constant force would accelerate the object steadily. However, it would require a steady force to propel the object through air even without acceleration. And the faster it went the more resistance it would meet.
A vertically launched object When is the acceleration due to gravity greater when ascending from the top or descending?
As long as the object stays somewhere near the surface of the earth, the acceleration due to gravity is constant, whether the object is moving up, down, sideways, or not moving at all.
When an object reaches terminal velocity what is the net force acting on the object?
When an object is at terminal velocity, the two forces due to gravity and drag are equal, so the object ceases accelerating. Its motion is constant and vertically downward.
What happens to the acceleration due to gravity of an object in projectile?
The acceleration due to gravity of an object in projectile motion remains constant throughout its motion. Gravity acts vertically downward and causes the object to accelerate at a rate of approximately 9.81 m/s^2.

What is vertically symmetrical?
to feflect an object so the reflected object is the right way up
Why don't you do any work when you carry an object art a constant velocity?
Well, if you do that for a while, you could certainly raise a sweat, and you would say that you've done a lot of work. But in the strict Physics definition of "work", none of it has been done to the object you carried. The strict definition is: Force acting through a distance. Referring to the object you carry: -- You don't move it vertically. You just hold it there against the force of gravity, but your vertical force doesn't move it up or down. So no work is done vertically. -- Horizontally, the speed is constant. No force is required to maintain a constant speed, so no work is done horizontally either.
If the mass of an object does not change a constant net force on the object produces a constant what?
If the mass of an object does not change, a constant net force applied to the object will produce a constant acceleration according to Newton's Second Law (F=ma). This means that the object will continue to accelerate at a constant rate as long as the force is applied.
Why does the speed dcreses when an object is thrown vertically up?
The speed decreases when an object is thrown vertically up because of the force of gravity acting against the object's upward motion. As the object goes higher, the force of gravity slows it down until the object reaches its maximum height, where its speed momentarily becomes zero before accelerating back downward.
If the speed of an object does not changed then the object is traveling at a?
If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
Is the momentum of an object moving in a circular path at a constant speed is constant?
determine if the momentum of an object moving in a circular path at constant speed is constant.
