The equation for displacement.
What is Δx=(1/2)(a)(t^2) + (v0)(t)?
This is the definition of Newton's first law.
What is "an object will stay at rest or in uniform acceleration till an external force is acted on it?"
When an object has constant velocity, this is what the forces are.
What is the forces are balanced?
If the sun collapsed suddenly to become a black hole, the Earth would continue to do this
It is when the only force exerted on the object is force gravity.
What is freefall?
This is the value that can be found from taking the area under a velocity-time graph.
What is displacement?
This is the definition of the law of conservation of energy.
What is "energy cannot be created nor destroyed, only transfered?"
When you twirl a ball in a circle above your head this is the direction of the tension on the ball.
What is toward the center?
This is the speed of light (m/s).
What is 300 million meters a second?
On the moon what would hit the ground first if dropped at the same time from the same height: a bowling ball or a feather?
They would hit the surface of the moon at the same time.
It is the acceleration of an object when velocity is constant.
What is zero acceleration?
It is the equation for Netwon's second law.
What is f=ma?
To break a board, a typical karate chop delivers 3000 N of force to the board. This is the force that the board exerts on the hand during the chop.
What is 3000N?

A block of wood is floating on water. If you push down on the block until it is completely submerged, this is what happens to the buoyant force acting upon it.
What is the bouyant force increases?
The effiel tower does this in the winter as compared to the summer
What is shrink?
A force applied to a rocket gives it an upward acceleration equal to 2 times the acceleration of gravity. This is the magnitude of the force.
What is three times the weight of the rocket?
If a 5 kg object is dropped from rest at a height of 12.5 m this is how long it will take for the object to hit the ground.

What is net torque equals zero?
Consider one horizontal circular path that a ball makes on the inside surface of a cone. This is the normal force on the ball compared to mg.
What is it is greater than mg?
