Force & Motion
What is a Force?
A push or pull
Red,orange,yellow,green,blue,indigo,violet.
What is the Law of Conservation of Energy?
Energy cant be created nor destroyed, only changed forms.
How does a screw relate to a Inclined Plane?
A screw is basically a wrapped ramp.
What is speed?
A measure of distance over time, but without direction.
What is the formula for Force?
Force = Mass X Acceleration
A disturbance that transfers energy from place to another without permanently replacing the particles of the medium.
What is Work?
Force applied over a distance; measured in Joules(J)
What are the six types of simple machines?
Lever, Wheel and Axle, Pulley, Inclined Plane, Wedge, and Screw.
What is the formula for velocity?
Velocity = Distance / Time with a direction.
What is Newton's first law?
An object in motion, stays in motion and an object at rest stays at rest, unless acted upon by a net force.
What are the key properties of waves?
Wavelength, Frequency, Amplitude
What is Power?
The rate at which work is done, measured in Watts.
Which simple machine is a doorknob an example?
Wheel and Axle
What is the velocity of an object that is moving 6 meters in 2 seconds east?
3 m/s east
How does Mass infect interia?
More Mass means more inertia, which means more force to accelerate.
What Wave requires a medium?
Mechanical
What is potential energy?
Stored energy
Which simple machines has a fulcrum?
The rate at which an object changes position, including direction?
Velocity.
How does friction affect motion?
It slows things down like a bike coasting to a stop.
The bending of a wave around a barrier or through an opening.
What is Kinetic Energy?
The energy an object has due to its motion.
Which simple machine has slanted sides and is used to cut and split things apart?
A Wedge.
What is the formula to find average velocity: displacement divided by this.
Time
