100
What is Kinetic Energy?
The energy of motion.
100
What is motion?
A change in position over time.
100
What is the net force of a balanced force?
0 Newtons.
100
True or false: Gravity is a force.
True.
100
What is science?
The systematic study of natural events and conditions.
200
What is Potential Energy?
Stored energy.
200
What is speed?
A measure of how far something moves in a given amount of time.
200
What is net force?
The combination of all the forces acting on an object.
200
Is gravity a force that can act at a distance?
Yes.
200
What is empirical evidence?
Ex: observations, measurements, and other types of data scientists gather.
300
What are two factors that Kinetic energy depends on?
Mass and speed.
300
What is the formula to find average speed?
Speed=distance divided by time or s=d/t.
300
What is inertia?
The tendency of all objects to resist any change in motion.
300
What is gravity?
A force of attraction between objects that is due to their masses.
300
What is a dependent variable?
A variable that depends on something to cause the change.
400
What does gravitational potential energy depend on?
Mass and the object's height above the ground.
400
What is velocity?
Speed in a specific direction.
400
What is Newton's first law?
An object at rest remains at rest, and an object in motion maintains its velocity unless it experiences an unbalanced force or the law of inertia.
400
What 2 things does gravity depend on?
Distance and mass.
400
What is a scientific theory?
A well-supported explanation about the natural world.
500
What are the 2 types of energy?
Potential and Kinetic Energy.
500
What is a vector?
A quantity that has both size and direction.
500
What is the relationship between force, mass, and acceleration in a mathematical equation?
F=ma.
500
What can gravity affect?
Weight.
