• Scalar
• Vector
• Neither

Which scenario is an example of an object having BALANCED forces?

• A student pushes a crate across the floor.
• A car is accelerating as it travels on Dickson Street.
• A book is sitting on the table.
• All of the choices

If the net force acting on an object is 10 Newtons (N) East, is the forces balanced or unbalanced?

• Balanced
• Unbalanced
• There is not enough information to determine the answer.

Look at the image. Are the forces balanced or unbalanced? What is the net force?

• Unbalanced: 30 N to the right
• Balanced; 0 N
• Unbalanced; 0 N
• Balanced; 15 N to the right
• Unbalanced; 15 N to the right

Look at the image. Are the forces balanced or unbalanced? What is the net force?

• Balanced: 0 N
• Unbalanced: 0 N
• Balanced: 30 N
• Unbalanced: 30 N to the left
• Balanced: 60 N

Which force keeps you from falling through the floor if you are sitting on a chair on the floor?

• Applied force
• Gravity
• Normal force
• Air resistance

What occurs to the GRAVITATIONAL FORCE if the MASS of two objects increase?

• increases
• decreases
• stays the same

Which of the following is TRUE concerning weight and mass?

• Weight and mass are the same.
• Weight and mass are both forces.
• Weight is a force and mass is a measure of the amount of matter an object contains.
• Weight increase as mass decreases.

What factor(s) influence friction?

• Surface types
• Mass
• Mass and Surface Type
• None of the choices
