Gravity.
A change in speed or direction is caused by a force and is called acceleration.
A change in velocity is caused by a change in acceleration. Objects do not speed up, slow down, or change direction unless they are pushed in some way. The acceleration (a) of an object with mass (m) produced by a given force (F) may be calculated using the equation a = F/m.
bcz it need alarge man force
Yes, a force can cause an object to move, or to change its speed or direction. A net force that is non-zero is one that acts in this manner, and it represents the "sum" of the forces acting on an object. If the net force on an object is not zero, it is some number, and this represents a force that will act on an object to accelerate it.
The change in an object's motion, is simply force.The object cannot change motion unless acted upon by an outside force. For example: If I throw a baseball, it will never stop unless acted upon by gravity (or the outside force). Or the outside force could be it smacking into a wall or your friends head.
Plate tectonics.
Force.
Mechanical change
The convection forces of plate tectonics.
pollen grains are attracted by a magnetic force
a change in a objects velocity is caused by a unbalanced force :)
centrifical
yes
Continental drift :)
force! (i think) It was in my science book... so that is what i am assuming!It is actually an unbalanced force not just a force. -Kelsey Munroe
the movement of convection currents in the mantle is the cause of plate motion.
