Forces

What is force?

• The rate of an object's motion with direction

• The rate of an object's motion

• any push or pull

What is acceleration?

• The rate of an object's motion

• How fast an object's speed changes

• Any push or pull

As force increases, acceleration __________.

• increases

• decreases

• stays the same

What are balanced forces?

• Equal forces that don't cause change in an object's motion

• The resistance in motion

• The total force of an acting object

• Unequal forces that cause change in an object's motion

What happens when forces are unbalanced?

• It will cause change in the object's motion

• It will not cause change in the object's motion
