Newton’s second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. F=ma (Force = Mass times Acceleration).
Pick a sport to watch in the Winter Olympics.
Watch what the athletes do to move forward or backwards. What are they using to apply a force? Do you think the athlete’s weight matters when competing in their sport? What does their weight influence?
Experiment: find four different balls around your house. Examples would be a baseball, golf ball, ping pong ball, and marble.
Record their weights or if you do not have a scale, list them from lightest to heaviest.
Create a starting line on a smooth surface. Set the ball at the starting line and then using a straw blow at the middle of the ball to get it to move forward.
Do you think it moved in slow, medium, or fast speed. Write the speed you think it moved next to the list you created for the weights. Do this for each ball.
Which ball moved the fastest? Which one moved the slowest?
Did you use the same amount of force through the straw. If you didn’t, try blowing on them again using the same force with each through the straw.
Why do you think the heavier ball moved the slowest?
F=ma The heavier the object, the more force is needed to move it. With the same force applied it will move slower because it is heavier (more mass).
