Exploring Free Body Diagrams in Two Dimensions

What is the initial condition of the surface in the two-dimensional system?

• It is sticky.

• It is rough.

• It is frictionless.

• It has high friction.

What happens to block M1 when block M2 starts accelerating downward?

• M1 remains stationary.

• M1 accelerates to the left.

• M1 moves upward.

• M1 accelerates to the right.

How are the magnitudes of the accelerations of M1 and M2 related?

• M2's acceleration is half that of M1.

• M1's acceleration is double that of M2.

• They are equal.

• They are different.

What force acts upward on M1 from the surface?

• Frictional force

• Tension force

• Gravitational force

• Normal force

What is the direction of the tension force acting on M1?

• To the right

• To the left

• Downward

• Upward

What is the weight force acting on M2 represented as?

• M1 * a

• M1 * g

• M2 * g

• M2 * a

Why must the weight force vector of M2 be longer than the tension force vector?

• To show that M2 is heavier than M1.

• To indicate that M2 is accelerating downward.

• To indicate that M2 is moving upward.

• To show that M2 is stationary.

What is the sum of the forces in the y direction for M1?

• Equal to the tension force

• Equal to zero

• Equal to M1 * g

• Equal to M1 * a

What is the equation for the tension force in the x direction for M1?

• T = M2 * a

• T = M2 * g

• T = M1 * a

• T = M1 * g

How are the equations for tension in M1 and M2 related?

• They are independent.

• They are unrelated.

• They are equal to each other.

• They are inversely proportional.
