The physical property of matter that describes an object's resistance to a change in its state of motion.
What is inertia?
he basic algebraic equation used to represent Newton's Second Law.
What is F = ma (Force = mass × acceleration)?
Newton's Third Law states that for every action, there is an equal and this kind of reaction.
What is opposite?
A rocket blasts off into space by expelling hot gas downward out of its engines.
What is the Third Law?
The rate of change of velocity over time.
What is acceleration?
According to the First Law, an object at rest will remain at rest unless acted upon by this type of force.
What is an unbalanced (or net) force?
The standard metric (SI) unit used to measure force.
What is a Newton (N)?
Forces always occur in these pairs, meaning a single, isolated force cannot exist.
What are action-reaction pairs?
It is much easier to throw a baseball than a heavy concrete block.
What is the Second Law?
The pulling force exerted by a string, rope, chain, or cable when it is pulled tight by forces acting from opposite ends.
What is tension?
This measurement directly determines how much inertia an object has.
What is mass?
If you double the force applied to an object but keep its mass the same, this will also double.
What is acceleration?
When you take a step forward on the ground, this is the entity that pushes you forward.
What is the ground? (You push backward on the ground; the ground pushes forward on you)
A magician successfully pulls a tablecloth out from underneath a set of dishes without knocking them over.
What is the First Law?
A vector quantity that includes both the speed of an object and its direction of motion.
What is velocity?
The reason why Mr. Rush feels a shock when he brakes his car.
What is Inertia?
The amount of net force required to accelerate a 5 kg bowling ball at a rate of 3 m/s².
What is 15 Newtons?
The reason a firearm recoils or "kicks back" into a shooter's shoulder when fired.
What bullet being propelled forward? (The action is pushing the bullet forward, the reaction is the bullet pushing the gun backward).
A driver is thrown forward against their seatbelt during a sudden head-on collision.
What is the First Law?
This specific term describes the force of gravity acting on an object's mass.
What is weight?
The invisible force that ultimately brings a rolling soccer ball to a stop on a field, preventing it from moving forever.
What is friction?
If an equal force is applied to an empty shopping cart and a fully loaded shopping cart, this one will have a lower acceleration.
What is the loaded shopping cart? (Greater mass results in less acceleration for the same force). [1]
Even though a bug and a car windshield exert equal and opposite forces on each other during a collision, the bug suffers total destruction due to this stark difference.
What is its much smaller mass? (Resulting in a massive, fatal acceleration).
A paddler moves a canoe forward through the water by pulling the paddle backward.
What is the Third Law?
The condition of an object when the net force acting on it is exactly zero, meaning it is either at rest or moving at a constant velocity.
What is mechanical equilibrium?
