friction
The force that resists the motion of the crate is the force of friction between the crate and the floor. This frictional force acts in the opposite direction to the pushing force applied by the person, making it harder to move the crate.
A person pushing a car to start it. Wind pushing a sailboat forward. A person pushing a door open. A hand pushing a book across a table. A swimmer pushing through the water.
Two examples of pushing forces are a car's engine pushing the car forward, and a person pushing a heavy object across the floor.
A person pushing a bookshelf across the room. A car engine pushing the vehicle forward. Wind pushing against a sailboat, propelling it forward. A person pushing a swing to make it move. A piston pushing down in a combustion engine.
An example of action and reaction forces is a person pushing against a wall. The action force is the person pushing on the wall, while the reaction force is the wall pushing back on the person with an equal force in the opposite direction.
Pushing a door open. Pushing a shopping cart. Pushing a car that ran out of gas. Pushing a heavy object across the floor. Pushing a person on a swing.

When a person jumps off a diving board, the force pushing the person upward (reaction force) is caused by the person pushing down on the diving board (action force). The reaction force is equal in magnitude and opposite in direction to the action force, according to Newton's third law of motion.
When a parachute is deployed, the action force is the air resistance pushing against the fabric of the parachute, and the reaction force is the fabric of the parachute pushing back against the air. This interaction creates drag, slowing down the descent of the person or object attached to the parachute.
According to Newton's third law of motion, for every action there is an equal and opposite reaction. Therefore, the force acting on the person pushing the wall is also 35 N in the opposite direction.
Some examples of action and reaction forces are: 1) a person pushing against a wall – the person exerts a force on the wall (action), and the wall pushes back on the person with an equal but opposite force (reaction), 2) a rocket propelling itself in space – the rocket expels gas downwards (action), causing the rocket to move upwards (reaction), and 3) a book resting on a table – the book exerts a downward force on the table (action), and the table exerts an equal force upwards on the book (reaction) to support it.
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.

When a force is exerted on a box, an equal and opposite reaction force is generated by the box. This is described by Newton's third law of motion, stating that for every action, there is an equal and opposite reaction.
