Circular Motion
An object is accelerating if it is speeding up, slowing down, or doing this.
What is changing direction?
Work is a scalar quantity but has a positive or negative sign because of this.
What is the gain (+) or loss (-) of energy by the system?
This term means 'inertia in motion.'
What is momentum?
This is another word for vibration.
What is oscillation or periodic motion?
This type of electricity is a build up of charge.
What is static?
This term means center-seeking.
What is centripetal?
When the force and distance are in the same direction, this is the value of theta.
What is zero degrees?
This is the mathematical relationship between mass and velocity in the momentum formula.
What is inverse?
This is the definition of a wave's period.
What is time for one cycle?
This type of charge results when an object loses electrons.
What is positive?
This type of force causes an object to move in circular motion.
What is a centripetal force?
This is how an object can be moving but no work is being done on the object.
What is moving at constant velocity? (Fnet=0)
OR, What is force and direction are at 90 degrees?
True or False? Explain.
A bigger object always has a higher momentum.
What is false. A smaller object could me moving at a very high velocity and have more momentum than a bigger object.
A mechanical wave is a transfer of _______ caused by a _______.
What is energy and vibration? (Must be in this order)
The electric force is this type of force.
What is a field force?
These are 4 examples of forces that can serve as a centripetal force.
What are normal, tension, friction, gravity, or spring force?
If a force is applied at an angle, this vector is responsible for the net force in the direction of the object's motion.
What is a component vector?
This quantity has the symbol 'J'.
What is impulse?
What is matter?
The direction of electric field lines is determined by this.
What is the direction of a positive test charge?
This is how an object can be moving at constant speed but is still accelerating.
What is changing direction?
A constant force causes this motion.
What is a constant acceleration?
The impulse-momentum theorem is derive from this law.
What is Newton's 2nd Law?
OR, What is F=ma?
Particles affected by this type of wave vibrate parallel to the wave's energy.
What is a longitudinal wave?
This is how electric force is created.
What is 'when a charge is placed in an electric field'?
