Circuits
What does a faster current mean?
Faster moving electric charges.
What is a wave?
a disturbance that travels or propagates from the place where it was created
Which state of matter has a definite shape and volume?
A solid.
If the mass of a ball is increased 4 times from its original mass, then its kinetic energy will?
Increase four times.
According to Newtons 1st Law of Motion, what will a moving object that's not acted on by unbalanced force do?
Stay in Motion
What do open the Circuits test?
Weather an objects is a conductor or and insulator.
What is a longitudinal wave?
a type of wave where the particles of the medium vibrate parallel to the direction the wave travels.
Which state of matter has no definite shape or volume?
A gas.
What two variables does kinetic energy depend on?
Mass and velocity.
Which of Newtons Law of Motion's explains inertia?
Newton's First Law
What is electricity?
the flow of electrical charge, primarily electrons, from one point to another.
What is a amplitude?
the maximum displacement of a point on a wave from its resting position.
What happens to the particles in a substance when it changes from a liquid to a solid?
They move slower and lose energy.
Which is required to move a body from a resting position?
Which Newton's Law of Motion states that for every action there is an equal and opposite reaction?
Newtons 3rd Law
What is the difference between a series and a parallel circuit?
a series circuit has components connected end-to-end, creating a single path for current flow, while a parallel circuit has components connected across the same two points, creating multiple paths for current.
What is a transverse wave?
a wave where the movement of the medium is perpendicular to the direction the wave is traveling
Describe the process of sublimation.
The phase transition where a substance directly changes from a solid to a gas without becoming a liquid first.
If a 82 kg person is in an elevator moving at a speed of 5 m/s, then what is the person's kinetic energy?
1,025 J
What is the formula for Newton's 2nd Law of Motion?
F=ma
A parallel circuit resonance is used for magnifying?
voltage.
What is a mechanical wave?
a disturbance that travels through a material medium, transferring energy from one place to another.
What happens to the particles in a substance when it changes from a solid to a gas?
Gain energy, causing them to move faster and farther apart.
A 1500 kg car starts at rest and speeds up to 3.0 m/s. The input energy is 22,500 J. If 0.15 gallons were used up in the process. What is the energy content of the gasoline in Joules per gallon?
15,000 J/ gallons of water
What does Newtons second Law of Motion state about an objects acceleration?
Directly proportional to net force is in the same direction.
