100
When an object's distance from another object is changing.
What is motion?
100
Any object that orbits another object in space.
What is a satellite?
100
The combination of all the forces acting on an object.
What is net force?
100
This opposes motion.
What is friction?
200
A place or object used for comparison to determine if something is in motion
What is a reference point?
200
This means center-seeking.
What is the meaning of centripetal?
200
Forces acting on an object that combines and forms a net force of zero.
What are balanced forces?
200
You can measure friction and gravity in this unit.
What are Newtons?
300
A system of measurement.
What is International System of Units?
300
A satellite does not need this because it continues to move ahead due to its inertia.
What is fuel?
300
Forces acting on an object that combine and form a net force that is not zero.
What are unbalanced forces?
300
Friction acts in a direction ______ to the object's direction of motion.
What is opposite?
400
A system of measurements
What is the International System of Units?
400
This follows a curved path.
What is projectile?
400
If the net force on an object is zero, the motion of the object does not change.
What is Newton's first law?
400
Name the four types of friction.
What is fluid, sliding, rolling, static?
500
Scientists use SI units to describe this
What is the distance the objects move?
500
This has a greater horizontal velocity than a ball.
What is gravity?
500
The tendency of an object to resist a change in motion.
What is inertia?
500
______ is a measure of the amount of matter in an object and ________ is the force of gravity on a person or object at the surface of a planet.
What are mass and weight?
