Forces
A noncontact force of only attraction.
A frictional force opposing an object's motion through the air
Air Resistance
The single, total force acting on an object, found by adding all individual forces going in the same direction or subtracting forces going in the opposite direction
Net Force
Wave that moves in a parallel motion.
LONGitudinal Wave
Length from the rest position to a crest or trough.
WHAT IS amplitude?
A noncontact force of attraction or repulsion
Magnetic Force.
A set of forces exerted on an object, the combined force has size and direction
Unbalanced Forces
the scalar quantity representing a forces’ strength or size, independent of direction, typically measured in Newtons (N) or pounds (lb)
Magnitude
Wave that travels in a perpendicular motion.
TRANSverse Wave
Alternates with rarefactions.
WHAT ARE compressions.
Is described by its strength and direction.
Force
A set of forces on an object that cancel each other out - so there is no change in the motion
Balanced Forces
Acts in closed loops, typically pointing from the north pole to the south pole, with strength decreasing as distance from the magnet increases
Magnetic Field
Formula for Frequency
Cycles divided by the time
Frequency = Pitch
Sound Waves
An external push or pull exerted on an object by a person or another object that may cause it to change speed or direction
Applied Force
Can be measured in grams (g) and kilograms (kg)
Mass
Gravitational pull due to the mass of the object - measured in Newtons (N)
Weight
An adult is pulling a child in a wagon on a flat, level sidewalk. The force of friction acts against the forward motion of the wagon.
What will happen when the pulling force is less than the force of friction?
The wagon will come to a stop.
Lowest Frequency Wave
A contact supporting force that acts on an object lying on a surface and acts in a direction perpendicular to the surface
Normal Force
It opposes motion between two surfaces that are in contact and depends on the surface and mass
Friction
Makes apple fall
Gravity
When the length from crest to trough vertically is 8 cm and the amplitude is equal to the wavelength squared, then what is the wavelength.
2 cm
Yes or No
