The only equation I'm given is F=M*A but I don't know how to apply it when I have an angle as well.

In summary, to find the magnitude of net force given mass, angle, and acceleration, you can use the equation F=M*A. If the mass is on an inclined plane with an angle, you can decompose the gravitational force into two parts and then find the sum total of all the forces. The original question gives an example of a 725 gram block accelerating at 5.10 m/s squared at an angle of 14.0 degrees relative to horizontal.

If so, then if there's no friction you have just gravitational force downwards, decompose this force into two Parts, one Normal to the surface (but opposite to the Normal force), the other parallel to the plane of inclination.

Hopes that helped somehow, your post doesn't seem to be very clearly written.

Net force is the sum of all the forces acting on an object. It is a vector quantity, meaning it has both magnitude and direction.

To calculate net force, you must first identify all of the individual forces acting on an object. Then, you can use vector addition to find the sum of these forces. The resulting magnitude and direction will give you the net force.

Individual forces act on an object in different directions and cancel each other out to some degree. Net force takes into account all of these forces to determine the overall effect on the object, whether it be a change in motion or a state of equilibrium.

Knowing the magnitude of net force is important because it allows us to understand the overall effect of multiple forces on an object. This information is crucial in predicting and explaining the motion of objects.

Yes, net force is measured in units of Newtons (N). This is a derived unit, equal to the mass of an object multiplied by its acceleration (F=ma).
