Force and Translational Dynamics
An object is suspended from a ceiling by two ropes. The tension in each rope is 10 N, and the ropes are at right angles to each other. If the object is in equilibrium, what is the weight of the object?
A block is placed on an inclined plane with friction. A force is applied to the block to keep it from sliding down. To determine if the block is in equilibrium, what must you do?
An object is placed in an elevator accelerating upwards. How would an observer inside the elevator describe the forces acting on the object?
Two forces act on an object: 3N to the right and 4N upwards. What is the magnitude of the net force on the object?
Which of the following best describes balanced forces?
A tug-of-war has two teams. Team A is pulling with a force of 500 N, and Team B is pulling with a force of 450 N in the opposite direction. What will happen?

Two forces act on an object. Force 1 is 20 N at an angle of 30 degrees relative to the x-axis, and Force 2 is 30 N at an angle of 60 degrees relative to the x-axis. What is the net force in the x-direction?
An object is at rest. According to Newton's First Law, what will the object do if no net force acts on it?
Which of the following conditions must be met for an object to be in translational equilibrium?
