Hello! I’m Mr. Accel short for “Acceleration”. Welcome to another fun-filled adventure as we take the journey to the world of Physics. This time, we will be talking about the 2nd Law of motion, Acceleration. So, fasten your seatbelt as we go and learn! Let’s go!

This Intervention material is design to give you a wide understanding

about the different concepts about Acceleration relevant to forces and mass.

Upon finishing this SIM, the reader is expected to:

• Define and know what and how Acceleration works.

• Identify and understand the concepts of Acceleration.

• Know what is stated in the Law of Acceleration,

• Solve scientific Problems using Acceleration formula involving mass and

force.

Now that you know that you will be learning, let’s take a

little review about the topic…..

Force and acceleration are proportional to each

other—the amount of force is equal to

the amount of acceleration. The greater the force

exerted on an object, the more it will

accelerate. For example, the harder you kick a ball,

the farther and faster it will travel.

The opposite is true of mass. The more mass an

object has, the less it will accelerate. If you

kick a tennis ball and a bowling ball with the same

amount of force, the heavy bowling ball is

going to move slower and go a shorter distance

than the tennis ball. A heavier object

requires more force to set it in motion.

Have you watched what happens to a pile of leaves on awindy day? A light breeze might gently scatter the leaves across the lawn, but a huge gust of wind would send the leaveswhirling into the air. If the wind got stronger, the leaves would soar through the air even faster—and your bike might even tip over, too! Remember, Newton’s First Law tells us that an object will stay at rest or in motion unless a force changes it. In his second law, he explains how unbalanced forces cause objects to accelerate,or move faster. Newton’s Second Law says that an object’s acceleration depends on two things: force and mass. As the force exerted on an object increases, the acceleration will increase. That’s why when the gentle breeze turns into a strong gust, the leaves move faster and farther. As the force of the wind increases, theAcceleration of the moving leaves increases, too. The relationship between acceleration and mass is just theopposite. The more mass something has, the less it will accelerate. Leaves are light and have very little mass, so they will accelerate quickly. Your bicycle, on the other hand, has much moremass than the leaves. The same gust of wind that blew the leaves into your neighbor’s yard might have scooted your parked bicycle only a few inches.
