force
friction
pushing an object. pulling an object
it could speed up or slow down, it depends which force is bigger and which direction the force is pushing/pulling etc.
a force
Force
An application of pressure versus an object, such as pushing or pulling.
the object will move
An object's motion can't change unless an external force is acting upon it. This is Newton's First Law of Motion.
applying a force to an object, (pushing, pulling, hitting, kicking etc.) can change its speed, its direction and its shape.
There are generally 4 forces which affect an object. These are: - weight force - the force acting downwards on the object - normal reaction force - the force acting upwards on the object - driving force - the force pushing the object on the horizontal plane (ie. left/right) - friction force (including air resistance) - the force pushing the object in the opposite direction to the driving force
a girl and a boy are pulling heavy crate at the same time with 10 units of force each . what is the net force acting on ythe object?
