This is the force that will slow and eventually stop a book sliding across a table.
What is friction?
This is Newton's Second Law.
What is F=ma?
Newton's Third Law says that for every action, there is this.
What is an equal and opposite reaction?
This state of matter generally has the highest density.
What is a solid?
This is the tendency of an object to resist changes in velocity.
What is inertia?
What is a Newton (N)?
The amount of force a wall exerts on you when you punch a wall.
What is an equal force in the opposite direction?
This state of matter generally has the lowest density.
What is a gas?
This is Newton's First Law.
What is, an object at rest will remain at rest until an external force acts upon it, and an object in motion will remain in motion until an external force acts upon it?
A 5kg object is moved with an acceleration of 2m/s^2. This is the force.
What is 10 N?
The alternate term for Newton's Third Law of Motion.
What is the Law of Action-Reaction?
This property of helium makes a helium balloon rise.
What is density (low density)?
This force opposes motion between two objects that are in contact.
What is friction?
A 1000kg car is moving with an acceleration of 2m/s^2. This is the force acting on the car.
What is 2000 N?
A book is resting on a table. This force pulls the book downwards.
What is gravity?
This is the mass of an object per unit volume, which tells us how tightly matter is packed.
What is density?
This is needed to change the motion of an object.
What is force?
A 10kg object is pushed with a force of 20 N. This is its acceleration.
What is 2m/s^2?
A book is resting on a table. This force pushes the book upward.
What is the normal force?
This is the principle that explains why objects float or sink in a liquid.
What is Archimedes' Principle?
