Position and Motion
It is found using distance and direction from a reference point.
What is Position?
A push or a pull.
What is a force?
Two equal and opposite forces that act on two different objects.
What is a force pair?
Gravity and magnetism are this type of force that act without direct contact.
What is a noncontact force?
These transfer energy from one place to another without transferring matter.
What are waves?
A change in position over time.
What is Motion?
A change in motion is produced by them.
What are unbalanced forces?
The law that states when you push on a wall, the wall pushes back on you with equal force but in the opposite direction.
What is Newton's third law?
The weight of an object on Earth depends on these two factors.
What are mass and gravity?
These kind of waves require a medium to travel.
What are mechanical waves?
The change in position from start to finish in a straight line.
What is displacement?
A change in velocity over time.
What is acceleration?
A swimmer pushes water backward with their hands and water pushes the swimmer this direction.
What is forward?
Gravity between two objects decreases as this increases.
What is the distance between them?
The number of waves that pass a point in one second.
What are Hertz?
Magnitude and direction.
What is a vector?
Acceleration depends on these two factors.
What is net force and mass?
The force the wall is exerting on you, if you push on the wall with 30 newtons of force.
What is 30 newtons of force?
Gravity between two objects increases as this increases.
What is their mass?
These type of waves travel parallel to the direction of energy transfer.
What are longitudinal waves?
How far an object travels per unit of time.
What is speed?
A box is pushed right with 20 newtons of force, friction pushes left with 10 newtons of force. This is the net force.
What is 10 newtons to the right?
When colliding objects bounce off of each other.
What is an elastic collision?
As the mass of an object increases, this is what will happen to it's weight on Earth.
What is increase?
The energy of an electromagnetic wave is directly related to it.
What is the frequency?
