there is gravity is sell keeping it down
True. A force acting in the opposite direction to the motion of a moving object will slow it down or stop it. This is known as friction or drag.
Yes, according to Newton's first law of motion, an object will remain in its state of motion (either at rest or moving at a constant velocity) unless acted upon by an external force. In order to keep an object moving, a force must be continuously applied to overcome any friction or resistance that might slow it down.
The opposite force to friction is momentum. Because friction stops an object from moving or slows an object down, momentum keeps it at speed.
Yes, but an object with net force of zero may still be moving. The net force is zero if the object is not accelerating.
Force can make matter move: that's true. Force cannot stop matter from moving: untrue. When u run, can someone catch you by force u to stop? Yes they can.
True. When the net force on an object is zero, it means that all the forces acting on the object are balanced and cancel each other out. This can result in the object either being at rest or moving at a constant velocity.
True, friction is a force that opposes the motion of an object when it is in contact with another surface. Friction can cause the object to slow down or stop moving.
Centripetal force is not a distinct force but rather the net force acting on an object moving in a circular path. It is always directed towards the center of the circle and is required to keep an object moving in a circular path. It does not have its own cause but arises as a result of other forces acting on the object.
true
No, when the forces acting on an object are unbalanced, the object will accelerate in the direction of the greater force. If the forces are unbalanced and the object is already moving, its speed or direction of motion will change.
true
Centrifugal force is the apparent outward force experienced by an object moving in a curved path. It is not a true force, but rather a result of the inertia of the object trying to continue moving in a straight line.
