pascal
That is usually described in units of pressure - force per unit area. The SI unit for pressure is the pascal, equivalent to newton/meter2.
When the force is doubled the pressure is doubled as well. Read Newton's law.
What is the torque of a 500 Newton force applied to a 30 meters wrench?
Force = pressure x area. Calculate the area, then multiply that by the pressure.* Don't forget to convert the pressure to pascal first. * The answer will be in newton.
The molecules in a gas are moving in all directions and they constantly crash into the surface and bounce back. This is just like when you throw a tennis ball against a wall and it bounces back: the wall changes the momentum of the ball by changing its velocity, meaning the wall exerted a force on the ball and, by Newton's laws, the ball exerted an equal and opposite force back on the wall (just the wall is so massive it doesn't show it). With air molecules this happens many many times, so this collectively exerts a pressure (which is just a force per unit area) on whatever surface is in contact with the gas. This pressure just depends on the temperature of the gas and how compact it is (its volume).

1 pascal
The pressure of 1 newton per 1 square meter is called 1 pascal. Pressure = force / area pascal = newton / m2.
1 pascal
A force of one Newton per square meter of surface area produces a pressure equal to 1 Pascal, which is abbreviated Pa. This is the definition of pressure in physics using SI units.
No, it is not. Pascal is the unit (SI) of pressure. 1 Pascal=1 Newton/metre2
First, you will have to convert the ton to units of force (about 10,000 Newton). Second, to convert the pressure to force, use the definition of pressure: pressure = force / area. In other words, the pressure required will also depend on the area over which the pressure is applied. Note 1 bar = 100,000 Pascal 1 bar = 100,000 Newton/m2

Newton's First Law: objects at rest tend to stay at rest, objects in motion tend to stay in motion. When the brakes are applied, the friction with the road surface is the force that stops the car -- on ice, this friction is greatly reduced.
