it has to do with gravity, weight, friction, torque, and force.....
simply put your lateral force (pushing from the side) has to exceed the friction caused by the box and the surface its on
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.
The force that prevents a heavy box from sliding along the floor when you push on it is friction. Friction is the resistance force that occurs when two surfaces come into contact with each other. It acts in the opposite direction of the applied force, creating a “grip” that keeps the box from sliding.
Pick a gear that's too heavy to pedal while sitting, get out of the saddle, and push it as hard as you can.
It's difficult to imagine such a fiction.
The opposite of "Push hard" or a hard push is an easy or light push.
force is push and pull
Sliding Friction If you push hard enough on the cardboard box filled with books, it will start sliding. If you stop pushing after the box starts sliding, it will slow down and stop. The force that acted on the box to slow it down was sliding friction. Sliding friction is the force that opposes the motion of two sliding surfaces in contact. Sliding friction exists between all sliding surfaces that are touching, such as the surfaces of the moving parts in a car's engine.
If you push a box until it moves, the forces are unbalanced. Your push overcomes the force of friction between the box and the ground, causing the box to accelerate in the direction of your push.
Because the air that is in the full box is being pushed while the other box that is empty has no air at all for it to be heavy.
The white push button on the top of the box.
first,push the left box in next,push the right box in then,push the middle box to the right or the left finally,go in and push the rock to the button and your free to go in! caution! Do NOT push the middle box straight in the middle!
you can push pull slide drag lift use a cart some tools
