When you are walking you are using Newton's third law. You apply a force ​
as you step down. At the same time, the surface of the ground exerts a force ​
on you. Because you are ​
than the ground, you are propelled up and​
.

Multiple Choice

For every action, there is a(n) ______________ reaction

1

opposite and equal

2

opposite and unequal

3

same and equal

4

same and unequal

Draw

Draw arrows to show where the rocket is pushing force and the opposite force that is equal and causes the motion of the rocket.

When you are shopping in the grocery story you are applying Newton's third law. At first the force you apply is ​
because there is very little to ​
. As you start to add objects the mass of the cart ​
. This causes you to have to apply a ​
amount of force to keep the cart moving. So, you are demonstrating that ​
requires more force to cause the same amount of acceleration

Summary

Motion that we see is due to the forces that are applied to and act on objects. Newton was able to develop three laws that explain the motion we see via the forces.
