Force & Motion Basics
This is the force of attraction between two objects with mass
What is gravity?
This Law states that an object in motion stays in motion and an object at rest stays at rest unless acted upon by an unbalanced force.
What is Newton's First Law (Law of Inertia)?
This type of magnet is temporary and requires an electric current to operate.
What is an electromagnet?
Sound is caused by these rapid back-and-forth movements.
What are vibrations?
The metric unit used to measure force.
What is a Newton (N)?
The rate at which an object changes its velocity.
What is acceleration
The tendency of an object to resist changes in its state of motion.
What is inertia?
The area around a magnet where its magnetic force is exerted.
What is the magnetic field?
This property of a sound wave is measured in Hertz (Hz) and determines the pitch.
What is frequency?
This is the resistance force that opposes motion between two surfaces in contact.
What is friction?
A push or a pull that can change an object's motion or shape.
What is a force?
A student pushing a wall, and the wall pushing back with equal and opposite force, is an example of this Law.
What is Newton's Third Law (Action-Reaction)?
A device that uses electromagnetism and motion to convert mechanical energy into electrical energy.
What is a generator?
Sound travels fastest through this type of matter.
What are solids?
The form of energy that involves the movement of charged particles.
What is electrical energy?
The measurement of how far an object travels over a period of time, without regard to direction.
What is speed?
If you apply the same force to two different objects, the object with the greater mass will have this type of acceleration.
What is less acceleration?
The three materials that are naturally attracted to a magnet.
What are iron, nickel, and cobalt?
The measure of a sound wave's intensity, which determines how loud the sound is.
What is amplitude?
A compass needle aligns with this invisible, global field.
What is the Earth's magnetic field?
A description of damage that can be temporary or permanent.
What is deformation?
The property of matter that is a measure of the amount of stuff in an object.
What is mass?
The two main components required to create an electromagnet.
What are a wire coil and a current/electricity (or an iron core)?
This phenomenon causes sound waves to bounce off a hard surface.
What is an echo?
This effect explains why the pitch of a siren sounds higher as it approaches you and lower as it moves away.
What is the Doppler Effect?
