Newton's 1st and 2nd Law Review

What is Newton's First Law of Motion?

• Force = mass x acceleration

• The resistance to move

• If the force remains the same, the more mass an object has, the less the acceleration.

• An object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an unbalanced force.

What is Newton's Second Law of Motion?

• Force = mass x acceleration

• The resistance to move

• If the force remains the same, the more mass an object has, the less the acceleration.

• An object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an unbalanced force.

What is Inertia?

• Force = mass x acceleration

• The resistance to move

• If the force remains the same, the more mass an object has, the less the acceleration.

• An object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an unbalanced force.

How does mass affect acceleration?

• Force = mass x acceleration

• The resistance to move

• If the force remains the same, the more mass an object has, the less the acceleration.

• An object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an unbalanced force.

When you give your friend a piggy back ride, you need to push harder on your legs, and it is harder to keep the same acceleration you had prior to picking up your friend.

I am riding a bus. The bus comes to a sudden stop, but the passengers still move forward.

A kid is running and slides down a slip and slide. He slides off of the slip and slide and the friction of the grass causes him to slow down and stop.
