PS: Chapter 4 practice

Mass is a measure of the force of gravity on an object

• True

• False

Most objects have at least two forces acting on them at all times

• True

• False

If opposing forces are unequal in strength, the net force is less than zero

• True

• False

The SI unit for weight is the newton

• True

• False

When two forces act on an object in the same direction, the net force equals zero.

• True

• False

When forces act in opposite directions on an object, they are subtracted to yield the net force

• True

• False

Every sport involves forces

• True

• False

Forces are always balanced when they act on an object in the same direction.

• True

• False

Whenever an object is stationary, it has no forces acting on it.

• True

• False

Two forces acting in the same direction always result in a stronger force.

• True

• False
