chapter 2 S.T.
The study of living things
What is life science?
Resistance to change in motion, Newton’s first law.
What is inertia?
Potential and kinetic
What are the two basic types of energy?
The way of learning about the natural world.
What is science?
Exerting a force on an object that causes the object to move some distance.
How do u do work?
Asking questions, evaluate information, and making decisions.
What does scientific literacy mean?
Multiple the objects mass by its velocity.
How can you determine the momentum of an object?
The energy an object has due to its motion.
What is kinetic energy?
The way of scientist having a attitude of doubt.
What is skepticism?
The force you exert
What is input force?
It helps you solve problems and answer questions throughout your life.
Understanding scientific principles helps you do what?
The strength of the force.
What does the length of the arrow tell you?
The energy associated with objects that can be compressed or stretched.
What is elastic potential energy?
Specific observations to make generalization.
What does inductive reasoning use?
When force is measured in Newton’s and distance in meters, the SI unit of work is the Newton-meter (N x m).
What is a Joule?
To analyze scientific claims by looking for bias and errors in the research, evaluating data, and identifying faulty reasoning.
How can you use scientific reasoning?
In the absence of outside forces like friction, the total momentum of objects that interact doesn’t change.
What does the law of conservation of momentum state?
Speed and mass
What does kinetic energy of an object depend on?
Using one or more of your senses to gather information. It also means using tools, such as a microscope, to help your senses.
What does observing mean?
The inclined plane, the wedge, and the screw.
What are 3 close machines related to simple machines?
Plants, animals, and microscopic life forms. They also study the human body.
What do life scientist study.
The attract to each other
What happens if two objects have the same mass?
Potential energy related to an objects height
What is gravitational potential energy?
Giving talks at meets, exchanging information on the internet, or publishing articles in scientific journals.
How do scientist communicate?
The output force of one simple machine becomes the input force of another simple machine.
What is within a compound machin?
