• What is a vector force?
• How do you add or subtract vector forces?
• How do you find the magnitude and direction of a vector force?
• How do you calculate the net force acting on an object?
• How does the angle between two vector forces affect the resulting net force?

Here are some more in-depth questions:

• A 20 kg object is pushed to the right with a force of 100 N, and to the left with a force of 50 N. What is the net force on the object, and in what direction is it acting?
• An object is acted upon by two vector forces: 10 N at 30 degrees north of east, and 20 N at 45 degrees west of north. What is the net force on the object, and what is its magnitude and direction?
• A force of 50 N is applied at an angle of 60 degrees above the horizontal to a 5 kg object on a frictionless surface. What is the acceleration of the object, and what is the magnitude and direction of the resulting net force?
• A 2 kg object is pulled to the right with a force of 10 N, and to the left with a force of 5 N. What is the acceleration of the object, and what is the magnitude and direction of the resulting net force?
• A 1000 kg car is traveling east at 20 m/s when it collides with a 2000 kg truck traveling west at 10 m/s. If the collision lasts for 0.1 seconds, what is the magnitude and direction of the resulting net force on the car?
