What type of equation would I use to find the resultant force?
Do I just add the vectors together? Or change them to X and Y variable?

PhanthomJay said:You can't just algebraically add them, since in general they have different directions. Split each vector into its x and y components, then add the x components together to get Rx, and add the y components together to get Ry, and use pythagorus to get the magnitude of the resultant force (R = sq. rt. of (Rx^2 + Ry^2)), and use trig to get the direction of the resultant force (Ry/Rx=tan theta.)
The resultant force equation, also known as the net force equation, is a mathematical representation of the total force acting on an object. It takes into account both the magnitude and direction of each individual force.
To calculate the resultant force, you must first determine the magnitude and direction of each individual force acting on the object. Then, you can use vector addition or trigonometric functions to find the resultant force vector. Finally, you can use the Pythagorean theorem to find the magnitude of the resultant force.
The resultant force equation uses standard units of measurement such as Newtons (N) for force and meters (m) for distance. However, it is important to make sure that all forces used in the equation are in the same unit of measurement.
The resultant force equation is used in many real-life applications, such as engineering, physics, and sports. It helps engineers design structures that can withstand specific forces, helps physicists understand the motion of objects, and helps athletes optimize their movements for maximum force output.
One common mistake when using the resultant force equation is not taking into account all the forces acting on the object. It is essential to consider all external forces, as well as any internal forces, when calculating the resultant force. Another mistake is using incorrect units for the forces, which can lead to incorrect results.
