Force and Motion Dynamics

Which of the following objects would require the most force to accelerate from rest, assuming the same acceleration is applied to each?

Two forces act on an object in the same direction: a 5N force and a 10N force. What is the net force acting on the object?

Two forces act on an object. Force A is 3N pointing East, and Force B is 4N pointing North. What is the magnitude of the net force?

Three forces act on an object: $\vec{F_1}$ = (2N, 0°), $\vec{F_2}$ = (3N, 90°), and $\vec{F_3}$ = (2N, 180°). What is the magnitude of the net force?

An object is moving at a constant velocity of 5 m/s in a straight line. Is this object in translational equilibrium?

An object has the following forces acting on it: $\vec{F_1}$ = 10N (right), $\vec{F_2}$ = 6N (left), and $\vec{F_3}$ = 4N (up). What force $\vec{F_4}$ is required to achieve translational equilibrium?

A block has several forces acting on it. Force A is 5N to the right, Force B is 3N to the left, and Force C is 4N upwards. An additional force, D, is applied. It is observed that the block remains at rest. Which of the following is the correct description of force D?

What happens to the motion of an object when balanced forces act on it?

A book rests on a table. Which of the following statements accurately describes the forces acting on the book?

A block is pulled at an angle across a surface with friction. Under what condition will the block move at a constant velocity?
