Distance-Time Graph
100
The ability to cause change.
What is energy?
100
You need a position and a reference point to determine an object's _____________.
What is location?
100
A push or a pull.
What is a force?
100
A force of attraction between objects due to their mass.
What is gravity?
100
Draw a distance-time graph, like the one on the board. Now, draw a line that shows an object that is stationary.
What is a straight horizontal line?
200
All moving objects have this.
What is kinetic energy?
200
The change in position over time.
What is motion?
200
Magnetic force, gravitational force, and electrical force.
What are non-contact forces?
200
Gravity _________ everything towards Earth's center.
What is pulls?
200
Draw a distance-time graph, like the one on the board. Now, draw a line that shows an object that is moving at a constant speed.
What is a straight diagonal line?
300
If you were to jump from a plane 10,000 meters from the ground with a parachute you would experience skydiving. As your position changes your ___________ would decrease.
What is (gravitational) potential energy?
300
How far something moves in a given amount of time.
What is speed?
300
Frictional force, normal force, air resistance force, and applied force.
What are contact forces?
300
The strength of the gravitational force between objects depends on these two variables.
What are mass and distance?
300
Draw a distance-time graph, like the one on the board. Now, draw a line that shows an object that has a positive acceleration.
What is a curved line up?
400
The sum of KE and PE due to an objects position.
What is ME (mechanical energy)?
400
When an object travels at the same rate over a period of time.
What is constant speed?
400
The combination of all forces acting on an object.
What is net force?
400
The amount of matter that is contained by an object.
What is mass?
400
Draw a distance-time graph, like the one on the board. Now, draw a line that shows an object that has a negative acceleration.
What is a curved line to the right?
500
There is a monkey swinging back and forth on a vine. Assuming there were no other forces for the ME to be transformed into, the monkey's ME would stay the same. This scenario supports this scientific principle about energy.
What is the law of conservation of energy?
500
A car traveling south at 100 kilometers per hour.
What is an example of velocity?
500
A satellite orbiting Earth will stay in motion indefinitely because there is little to no force to stop it. The scenario supports this scientific principle about motion.
What is Newton's first law of motion or the law of inertia or that an object in motion will maintain its velocity unless it experiences an unbalanced force?
500
Causes motion.
What is an unbalanced force?
500
Draw a distance-time graph, like the one on the board. Now, draw a line that shows an object that is moving, stopped, then returning to its original location.
What is a diagonal line going up to the right, then a straight horizontal line, then a diagonal line going down to the right?
