This is required to overcome an object’s inertia.
What is an unbalanced force.
Measure of an objects inertia.
What is mass (also the measure of the amount of matter in an object.)
According to Newton’s Second Law, if the force increased but the mass remained the same, what happened?
What is the objects acceleration increased.
A vector quantity, measured in Newtons, that tends to accelerate an object.
What is force also defined as a push or pull.
6 people are playing tug of war. 3 people are pulling on the right side, and 3 people are playing on the left side. On the right side, one person is pulling with the force of 60N. Another is pulling 30N, and the last is pulling with 15N. On the left side, one is pulling with 20N and another is pulling with 5N.
