Up-thrust (throw something into water)
Gravity (if you throw something up)
A force or acceleration
Not necessarily. If the force is balanced (equal in opposite directions), it will not change the object's motion. However, an unbalanced force will cause an object to accelerate in the direction of the force.
The forces cause the object to move in the direction of the net force. If there are two unbalanced forces in opposite directions, the object will go in the direction of the stronger force.
what starts to move an object is force because it's pushing on the object and what stop's the obect from moveing is force too because if the force is going the oppisit way its going to stop the object.
A basic physics answer for this is that a net force (or unbalanced force) will cause an object to accelerate, that is, cause the object to change its speed and/or direction.
Yes, an unbalanced force can cause an object to change its speed by accelerating or decelerating it. When the net force acting on an object is not zero, it will cause a change in the object's velocity, which includes changes in speed.
A force can accelerate an object, change the object's direction of motion, change the object's shape or size, cause the object to deform, or cause the object to rotate.
Three things that can cause a change in acceleration are a change in the net force acting on an object, a change in the object's mass, or a change in the direction of the force acting on the object.
A force can cause the object to accelerate, change its shape, or change its direction of motion.
If an unbalanced force acts on an object, it could cause the object to accelerate in the direction of the force, change its speed or direction of motion, or cause the object's shape to deform if the force is strong enough.
balanced forces are when the two opposite forces are equal and cause no change to the object e.g a car at a steady speed. unbalanced forces would cause the car to increase or decrease in speed
A net force from something outside of the system.
