Newtons 1ST Law
What does Newton’s First Law state?
An object with stay in motion, or stay at rest unless acted upon by an outside 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
This law helps explain why when you step on the gas in a car, it speeds up in proportion to how hard you press.
Newton's 1st law
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.
A soccer ball will keep rolling across the field unless it hits something, like a goalpost or a player. This happens due to this law.
Newtons 1st law
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
When two ice skaters push off from each other, they glide in opposite directions. This is an example of Newtons 3rd Law. TRUE OR FALSE.
TRUE
When you jump on a trampoline, you push down and the trampoline pushes you back up. This action-reaction pair is a perfect example of this law.
Newton’s Third Law
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
happens to a skateboarder when they push back on the ground with their foot.
the skateboard moves forward.
A rocket zooms into space thanks to this law, which explains how the expulsion of gas propels it forward.
Newton's 3rd law
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
A person jumping off a diving board doesn't exert any force on the board. TRUE OR FALSE.
FALSE
When you’re driving your car and slam on the brakes, the car’s passengers move forward, even though the car stops. This happens because of this law.
