aerodynamics
Force changes either the speed or the direction of motion, or both.
The change in direction of an object when a force is applied to it is called "acceleration." The acceleration of an object depends on the magnitude and direction of the force, as well as the mass of the object.
When an object changes direction in its motion, its velocity changes, and if the object is accelerating, its acceleration will also change direction. This change in direction is due to the application of a force in the opposite direction. The object's kinetic energy may also change as a result of this change in direction.
The weight of the object would change if gravity changes. cw: Yes, if the FORCE of gravity changes, the FORCE of the object in the downward direction changes.
The transfer of energy that causes an object to move in the direction of the force is called work. Work is defined as the product of the force applied to an object and the distance over which the force is applied in the direction of the force.
Friction
The transfer of energy that causes an object to move in the direction of the force is called work. Work is done when a force is applied to an object and causes it to move in the same direction as the force. The amount of work done is equal to the force applied multiplied by the distance the object moves in the direction of the force.
If a force does work on an object, the object's energy changes. The object will either speed up, slow down, or change direction depending on the direction of the force. Work is done when a force causes a displacement in the object's position.
A force can change the speed of an object by either accelerating or decelerating it. The direction and magnitude of the force will determine how the object's speed changes - an applied force in the direction of motion will accelerate the object, while a force in the opposite direction will decelerate it.
When an object has a net force acting on it, its velocity changes. The object will accelerate in the direction of the net force if the force is in the same direction as the object's velocity, decelerate if it's in the opposite direction, or change direction if the force is perpendicular to its velocity.
An unbalanced force is when there is a net force acting on an object that is not canceled out by another force, causing the object to accelerate in the direction of the larger force. This can lead to changes in the object's speed and/or direction of motion.
The transfer of energy that occurs when a force makes an object move in the direction of the force is called work. Work is calculated as the product of the force applied to an object and the distance over which the force is applied in the direction of motion.
