Newton's 1st Law of Motion
What is Newton’s 1st Law?
An object at rest will stay at rest, and an object in motion will stay in motion unless stopped
What is one word used to describe Newton's 2nd law of motion?
Acceleration
What is the planet we live on?
Earth
What does life science study?
Plants, animals, and humans
What does physical science study?
Physical science studies force and gravity.
What force can stop a rolling ball on the ground?
Friction
If you push a heavy box and a light box with the same force, which one will move faster?
The light box
What does earth science study?
The earth and weather
How many bones are there in the human body?
What is the force that pulls things toward Earth?
Gravity
If you slide a book on a table and it eventually stops, what force causes it to stop moving?
Friction
What happens if you apply a bigger force to an object?
It will accelerate faster
What is the most abundant gas in our atmosphere?
Nitrogen
Cardiac muscles are found in the heart.
Who discovered gravity?
Isaac Newton
What do we call the tendency of an object to resist changes in its motion?
Inertia
What is the relationship between an object’s mass and the amount of force needed to move it?
The more the mass, the more force needed to move it
How many states of matter are there and what are the names?
There are 4 states of matter. Gas, Liquid, Solid, and Plasma
How many types of cells are there and what is something one has that the other does not?
There are 2 types of cell: plant cell and animal cell.
The plant cell has a cell wall and the animal cell does not.
What is net force?
Net force is the total force working on an object.
Why do astronauts float in space according to Newton's 1st Law?
Because there is no gravity to stop them.
How would Newton’s 2nd Law explain why it’s harder to push a car than a bicycle?
The car has more mass, so it needs more force to accelerate
What is the center of the earth called?
The center of the earth is called the core
How is the human body organized?
If you push the car with 5 units of force to the right, and someone else pushes it with 3 units of force to the left, what is the net force?
5 units (to the right) - 3 units (to the left) = 2 units (to the right).
