Forces
Gravity and Motion
100
When a force causes an object to move in the direction of the force, this is accomplished.
What is work? work = force x distance
100
Velocity measures direction and this magnitude.
What is speed?
100
Energy is defined as the ability to do this.
What is work?
100
Force is measured in this unit.
What is a Newton?
100
A gravitational pull exists between any two objects that have this.
What is mass?
200
This is the unit we use to measure energy and work.
What is a joule? 1 Joule = 1 Newton x 1 Meter
200
This is how to calculate speed.
Average Speed = Distance/Time
200
These two things are needed in order for work to be done on an object.
What are force and displacement (movement)?
200
The tendency to resist change in motion.
What is inertia?
200
This factor affect objects at a distance and pulls them down.
What is gravity?
300
All objects in motion have kinetic energy. The amount of kinetic energy a moving object possesses depends on these two factors.
What are mass and speed?
300
The standard unit for measuring length.
What is a meter?
300
These types of energy make up mechanical energy.
What are kinetic and potential?
300
The combination of all forces acting on an object.
What is net force?
300
This is used to determine if an object is in motion.
What is a reference point?
400
Many objects have both kinetic and potential energy. For example, an airplane in flight has kinetic energy due to its movement, and potential energy because of its mass and distance from the Earth. The combination of potential and kinetic energy creates this form of energy.
What is mechanical? Mechanical Energy = Potential Energy + Kinetic Energy
400
To measure speed, the student needs these two instruments.
What is a clock or stopwatch? What is a tape measure?
400
This is a type of energy at an atomic level.
What is non-mechanical energy?
400
This is a contact force that opposes motion.
What is friction?
400
The force of gravity between Earth and any given object is the equivalent to this measurement.
What is weight?
500
This law states that energy cannot be created or destroyed, but can only be transformed into other forms of energy.
What is the Law of Conservation of Energy?
500
This is a measure of how fast something moves, or how far it moves in a given amount of time.
What is speed?
500
Potential energy is also called this name.
What is stored energy, or the energy of position?
500
This is the formula for calculating force.
What is Mass x Acceleration?
500
These two determines the weight of an object on any planet.
