Finding Net Force

What is the first step in finding the net force on an object?

• Calculating the mass of the object

• Drawing a force table

• Measuring the velocity

• Identifying the object's shape

What does the sigma symbol (Σ) represent in a force table?

• The division of forces

• The product of forces

• The sum of forces

• The difference of forces

How do you treat forces pointing to the left when calculating net force in the x-direction?

• As zero

• As negative

• As undefined

• As positive

What is the net force in the y-direction if you have 7 N up, 5 N up, 6.4 N down, and 5 N down?

• 0.6 N up

• 0.6 N down

• 1.6 N down

• 1.6 N up

If the net force is zero, what relationship can be derived from the force of tension (FT) and the force of friction?

• FT plus the angle equals the force of friction

• FT divided by the angle equals the force of friction

• FT times cosine of the angle equals the force of friction

• FT times sine of the angle equals the force of friction
