Thrust is a force that propels an object forward or upward by expelling gas or fluid in the opposite direction. It can increase the speed of an object if the net force of thrust is greater than the opposing forces like drag or gravity acting on the object.

Does friction act to slow down an object or speed up an object?
Friction acts to slow down the motion of an object. It opposes the relative motion between two contacting surfaces, reducing the speed of the object in motion.
What will never speed up an object?
A force that is perpendicular to the direction of motion of the object will never speed it up. This is because the force is unable to transfer any of its energy in the direction of motion.
Can slow down speed up or stop the motion of an object?
A force can slow down, speed up, or stop the motion of an object. For example, friction can slow down an object, while applied force can speed it up or stop it. The net force acting on the object will determine its resulting motion.
Friction will never speed up an object?
Friction always opposes motion, so it can never speed up an object. Friction slows down or stops an object's motion by acting in the opposite direction. To speed up an object, a force stronger than friction, like a push or a pull, is needed.
When an object is speeding up through the air are the forces of thrust and drag balanced?
When an object is speeding up through the air, the force of thrust is greater than the force of drag, causing the object to accelerate. For the object to continue speeding up, the thrust force must exceed the drag force. At a constant speed, these forces would be balanced.
What to componets make up the velocity of an object?
The speed of the object and its direction of motion.

A force that is perpendicular to the direction of motion of the object will never speed it up. This is because the force is unable to transfer any of its energy in the direction of motion.
When thrust and drag are equal why does the object still move?
When the forces on an object add up to zero, the object's acceleration is zero. Thatmeans the speed or direction of its motion doesn't change. It does not mean thatthe object isn't moving. A moving object would just keep moving at a constantspeed in a straight line.

What always causes a change in motion of the object?
An unbalanced force will always cause a change in the motion of an object. This change can involve speeding up, slowing down, changing direction, or a combination of these. Inertia, the tendency of an object to resist changes in its motion, is overcome by the unbalanced force, leading to the change in motion.
Does friction speed up an object?
Friction does not speed up an object; it creates drag and slows it down.
How does a negative or positive acceleration affect motion?
It can change the direction of motion or it can speed up or slow down an object.
What are some ways force can affect motion?
Force can change the speed, direction, or shape of an object's motion. It can cause an object to speed up, slow down, or change its path of motion. Force can also cause an object to deform or break depending on its magnitude and direction.
What does an object with a uniform motion have?
An object with uniform motion has a constant speed and direction. This means it travels at the same velocity without speeding up or slowing down.
