Newtons 1ST Law
What does Newton’s First Law state?
An object at rest stays at rest, and an object in motion stays in motion at constant velocity, unless acted upon by an external force.
What does Newtons 2ND Law state?
The more force applied to an object, the faster it will accelerate.
What is the scientists name that created Newtons Laws
Sir Isaac Newton
How does wearing a seatbelt relate to Newton's First Law?
When a car suddenly stops, your body wants to keep moving forward. A seatbelt provides the unbalanced force needed to stop you, preventing injury.
How does kicking a soccer ball relate to relate to Newtons 2ND law?
When you kick the soccer ball, your foot exerts a force on the ball. The harder you kick, the greater the force applied.
What does Newtons 3RD Law state?
For every action there is an equal and opposite reaction.
Why do objects eventually stop moving if no force is supposed to act on them?
Friction and air resistance slow the object and stop it.
The formula that expresses Newtons 2nd Law
F= Ma
What is inertia
Inertia is an object's resistance to a change in its state of motion.
When you kick a soccer ball, the ball accelerates because of...
Net force
Newton's 1st Law is often called this because it describes an object’s natural state of motion.
The quantity you are solving for when you divide force by mass.
Acceleration
