kinetic friction
The energy being used to push a heavy box across the floor is mechanical energy. The person pushing the box is converting their own muscular energy into kinetic energy to move the box.
friction
The kinetic energy of the ball in motion allows it to roll across the floor. As the ball is pushed or dropped, this kinetic energy is transferred to the ball's rotational motion, causing it to roll forward. Friction between the ball and the floor also plays a role in its movement.
The force diagram for a crate being pushed across the floor would typically show a horizontal force in the direction of the push, a normal force (perpendicular to the surface), and a frictional force opposing the motion. The sum of these forces determines the crate's acceleration or equilibrium.
The predicate in this sentence is across the floor. :)
The lava would form pillow basalts.
Because all the water ontop of you is being pushed down by gravity
Friction with the material it is pushed across and the gravitational pull of the earth are two factors that can cause the box to slow down. ================================== Gravity does not directly cause the box to slow down, but gravity is indirectly responsible for the existence of the friction force which does.
Yes, it will be released in 2014.
We can generally say that vacuum cleaners have motors. Carpet sweepers, in contrast, usually have a pair of brushes that rotate when the unit is pushed across the floor.
across the floor.
Mechanical energy is being used when a person pushes heavy boxes across the floor. The person's muscles convert chemical energy into mechanical energy to move the boxes.
