What happens when two forces act in the same direction?

• They cancel each other out.

• The stronger one prevails.

• Their strengths are added.

• Their sum divided by two is the total force.

The greater the mass of an object,

• the easier the object starts moving.

• the greater its inertia.

• the more balanced it is.

• the more space it takes up.

Compare the acceleration of the 1-kg object with that of the 2-kg object.

• 1kg object has more acceleration because it has less mass

• 1kg object has less acceleration because it has less mass

• 2kg object has more acceleration because it has more mass

• 2kg object has less inertia because it has more mass

Define the term inertia.

• the amount of matter in an object

• the amount of space an object takes up

• the tendency of an object to resist a change in motion, determined by mass

• The force that one surface exerts on another when the two rub against each other
