first law
If a car makes a sudden sharp turn, passengers feel "pushed" to the side because their bodies are trying to do this, according to the First Law.
What is move in a straight line?
If you double the force applied to an object while keeping its mass the same, this will also double.
What is acceleration?
When you sit in a chair, your body pushes down on the chair; this is the reaction force described by the Third Law.
What is the chair pushing up on your body?
This force always acts in a direction that opposes the motion of an object
What is friction?
If the net force acting on an object is exactly zero, the forces are described by this term.
What is balanced?
This famous scientist's concept of inertia challenged Aristotle’s idea that force is needed to maintain motion.
Who is Galileo Galilei?
This is the mathematical formula used to express Newton's Second Law of Motion.
What is Force = mass × acceleration?
According to the Third Law, forces always occur in these, never alone
What are pairs?
This type of friction occurs when you push against a heavy object that refuses to move.
What is static friction?
This type of force is required to cause any change in an object's motion or speed.
What is an unbalanced force?
This term refers to an object's tendency to resist any change in its motion
What is inertia?
A 10 kg bowling ball is pushed with 20 Newtons of force; what is its acceleration?
What is 2 m/s²? (20 N / 10 kg)
Newton’s Third Law is often summarized by saying that for every action, there is one of these.
What is an equal and opposite reaction?
Friction converts kinetic energy into this unusable form, often warming up the surfaces in contact.
What is heat (or thermal energy)?
forces have these two primary characteristics, which scientists represent using arrows.
What are size (magnitude) and direction?
Newton’s First Law states that an object at rest will remain at rest unless acted upon by this type of force.
What is an unbalanced or net force?
This is the unit for force, named after the same scientist, and is equivalent to one kilogram-meter per second squared
What is the Newton (N)
If you push on a wall, the wall pushes back on you with the same amount of force, but you don't move because the wall is much more massive.
What explains why pushing a wall doesn't make it move?
Engineers use ball bearings or lubricants like oil and graphite to achieve this effect on friction.
What is reducing it?
When two people pull on a rope in a tug-of-war with equal strength but in opposite directions, this is the net force.
What is 0 Newtons?
what is the primary factor that determines how much inertia an object has.
what is mass
In basketball, the harder you kick or throw the ball,the faster it travels to your teammate, demonstrating this law in action.
What is Newton's Second Law (or the Law of Acceleration)?
This law states that forces always occur in pairs, with one force being the "action" and the other the equal and opposite "reaction".
What is Newton's Third Law of Motion?
This is the force of attraction between all matter that is due to their masses
What is gravity?
To find the net force of two people pushing a heavy crate in the same direction, you should do this to their individual force values.
What is add them together?
