Applied force refers to a push or a pull.

• True

• False

What is the equation for normal force?

• N = m + g + cosθ

• N = m * g * cosθ

• N = m / g/cosθ

• N = m * cosθ

If the surface an object is on is flat then the normal force equals the weight of the object, but the force is directed in the opposite direction

• True

• False

The normal force is parallel to the surface the object is on.

• True

• False

What is the equation and unit for weight?

• Weight = mass / acceleration due to gravity

  Unit: kg

• Weight = mass + acceleration due to gravity

  Unit: N

• Weight = mass - acceleration due to gravity

  Unit: kg

• Weight = mass * acceleration due to gravity

  Unit: N
