| Second Law of Newton | Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

| Newton's First Law is also known as... | Inertia
🗑

| Third Law of Newton | For every action there is an equal and opposite re-action.

| A property of matter by which it remains at rest or in uniform motion in the same straight line unless acted upon by some external force | INERTIA

| What is the formula for Force? | F= M x A
Force= Mass times Acceleration

| VELOCITY | A speed with direction. For example, 20 mph North

| A net force of 15 N is exerted on an encyclopedia to cause it to accelerate at a rate of 5 m/s2. Determine the mass of the encyclopedia. |
Use Fnet= m * a with Fnet = 15 N and a = 5 m/s/s.
So (15 N) = (m)*(5 m/s/s)
And m = 3.0 kg

| Determine the accelerations that result when a 12-N net force is applied to a 3-kg object and then to a 6-kg object. | A 3-kg object experiences an acceleration of 4 m/s/s. A 6-kg object experiences an acceleration of 2 m/s/s.
