Understanding Newton's Second Law

What is the equation that represents Newton's Second Law?

• F_net = ma

• F_net = mg

• F_net = mv

• F_net = m/a

How is the net force related to individual forces in a system?

• Net force is the sum of all individual forces.

• Net force is the difference between the largest and smallest force.

• Net force is the product of all individual forces.

• Net force is the average of all individual forces.

What is the value of gravitational acceleration used in physics problems?

• 9.8 m/s²

• 10 N/kg

• 10 m/s²

• 9.8 N/kg

In a type 1 problem, what is the first step to solve for acceleration?

• Ignore the vertical forces.

• Directly use the given acceleration.

• Calculate all individual force values.

• Use the mass to find the net force.

In a type 2 problem, if the net force is directed to the right, what can be inferred?

• The net force is zero.

• The forces are balanced.

• The left force is greater than the right force.

• The right force is greater than the left force.
