100- What are the 3 types of potential energy?
1. Elastic 2. Gravitational 3. Chemical
100
100- Throwing a basketball into the air and then catching it again is an example of the energy transfer between _____ and _____ energy.
Kinetic and potential.
100
100- The distance an object moves in a unit of time is called
speed.
100
100- A force that is applied to an object without touching is called a(n)
non-contact force.
100
100- If you are driving 80 miles per hour, how many hours will it take to drive 80 miles.
1 hour
200
200- STORED energy due to the interaction of particles is called
potential energy.
200
200- Give an example of energy transfer, and name the types of energy involved.
Several answers may include: TV- Electic-> sound, light, thermal Microwave- Electric->radiant-> thermal -> mechanical Rock falling - potential -> kinetic
200
200- The speed AND direction of a moving object is called
velocity.
200
200- An attractive force that exists between all objects that have mass is called
gravity.
200
200- If you are driving 60 miles per hour, how far will you have travelled in one hour?
60 miles.
300
300- Energy that electromagnetic waves carry is called
radiant (light) energy
300
300- A force that resists the sliding of two surfaces is called
friction.
300
300- What is the formula for calculating speed?
speed = distance/ time
300
300- A push or pull on an object is called
force.
300
300-Find the average speed of an object that travels 600 miles in 20 hours.
30 MPH! speed = distance/time speed = 600 miles/ 20 hours speed = 30 miles per hour
400
400- The energy that is stored and released in the nucleus of an atom is called
nuclear energy.
400
400- Name three types of energy transfer involved in a TV.
Electric-> sound Electric-> light Electric-> thermal
400
400- The difference between the starting point and the final position of an object is called
displacement.
400
400- According to Newton's First Law of Motion, if the net force acting on an object is ZERO, the motion of the object (does, does not) change.
does not
400
400- Find the average speed of a person who runs 14 miles in 2 hours.
7 MPH! speed = distance / time speed = 14 miles / 2 hours speed = 7 miles per hour
500
500- The sum of kinetic and potential energy in particles is called
thermal (heat) energy.
500
500- According to the Law of Conservation of energy, energy can be transferred or transformed, but it CANNOT be __ and __.
created or destroyed.
500
500- The measure of the change in velocity is called
acceleration.
500
500- An action with an equal and opposite reaction is called a
force pair.
500
500- If a person drives 70 miles in 1 hour and continues to drive at that speed, how far will they have traveled in 2 hours?
140 MILES! 70 miles = 1 hour 70 x 2 miles = 1 x 2 hours 140 miles = 2 hours
