# How To Solve Force Problems In Physics As it sat there, the force of gravity was keeping it on the ground, while the ground pushed upward, supporting the ball.On a molecular level, the surface of the ball was holding itself together as the gas inside of the ball tried to escape.If you were a ball sitting on a field and someone kicked you, a force would have acted on you. Those forces would include gravity, the force of air particles hitting your body from all directions (as well as from wind), and the force being exerted by the ground (called the normal force).

And if you’ve ever been in a similar situation to this physicsforums commenter… So below I’ll go through a solution to a tension/Newton’s Laws problem pulled from an actual Physics 1 exam. Following our problem solving process, first things first, let’s restate the problem and identify exactly what we’re trying to find.

And once you wrap your head around how to set up your equations so that you don’t get ass-backwards with the direction of your tension forces, you’ll never have an issue with them again! We’re stating our assumptions (that the rope is massless and the pulley is frictionless), restating our known variables (the kinetic coefficient of friction, the two masses of the blocks, the acceleration of the system), and identifying the two unknowns that we need to find (the tension in each section of rope).

Physicists devote a lot of time to the study of forces that are found everywhere in the universe.

The forces could be big, such as the pull of a star on a planet.

This is because the rope itself is not accelerating in relation to the overall system (it remains taught as both masses continue to accelerate at 1 m/s^2), but is still providing the force required to keep mass A accelerating at 1 m/s^2.

Last, I’m applying the equation for kinetic friction to both of the masses, which acts in the opposite direction of the acceleration, and is proportional to the normal force acting on each mass (which ends up being equal to the weight because there are no other forces acting in the y-direction).

Second, the magnitude of the tension on cart 1 and cart 2 has the same value (since it's the same string).

This means I can draw the following two force diagrams for the two masses.

There is one totally important formula when it comes to forces, F = ma.

That's all there is, but everything revolves around that formula.

But the force by the hanging mass is 3gwhich is greater than 2.8g which implies that the system will be in motion and hence coefficient of kinetic friction will come into play. Hence the equation of motion, are 3g-T=3a{a=acceleration of the mass}. T-0.2508g=8a. Thus this gives you the Tension in the string.…
