The constant velocity of a falling object when the size of the upward force of air resistance matches the size of the downward force of gravity.
What is terminal velocity?
100
This causes a book on a table to remain at rest.
What is inertia?
100
The acceleration of an object depends on these two things.
What are mass and force?
100
This happens when one object exerts a force on a second object.
What is the second object exerts an equal and opposite force on the first object?
100
This thin structure surrounds a cell.
What is a cell membrane?
200
The condition an object is in when gravity is the only force acting on it.
What is free fall?
200
A book will remain at rest unless it is acted on by this.
What is an unbalance force?
200
This is unit of measure can also be described as 1 kg-m/s/s.
What is a Newton?
200
This is a property of a moving object that depends on the object's mass and velocity.
What is momentum?
200
This is an educated guess?
What is a hypothesis?
300
The curved path an object follows when thrown or propelled near the surface of Earth.
What is projectile motion?
300
When a car stops suddenly, your body tends to do this.
What is keep moving forward?
300
It would require this much force to move an object that weighs 10kg and accelerates at a rate of 45 m/s/s?
What is 450 kg-m/s/s?
300
Forces always act in this way.
What is pairs?
300
This is the inherited combination of alleles that makes us who we are. It can be found within our cells.
What is our genotype?
400
The tendancy of all objects to resist any change in motion.
What is inertia?
400
Objects fall to the ground at the same rate because the acceleration due to this is the same for all objects.
What is gravity?
400
These things are what cause acceleration.
What are unbalanced forces?
400
In a rocket engine, this force pushes the rocket upward.
What is reaction force?
400
This word describes a group of individuals of the same species that live together in the same area at the same time.
What is a population?
500
The speed of an object in a particular direction.
What is velocity?
500
All objects accelerate toward Earth at this rate.
What is 9.8 m/s/s?
500
Any change in velocity is called this.
What is acceleration?
500
For every action force, there is this.
What is and equal and opposite reaction force?
500
If a Tom Turtle, who has a genotype of RR, produces offspring with with Suzy Turtle, who has a genotype of Rr, how many offspring will the Turtles produce that will have a recessive phenotype?
