Kinetic Energy
The Energy of Motion
What is Kinetic Energy?
A push or pull that can change the motion of an object.
What is Force?
The sum of all the forces acting on an object.
What is Net Force?
The force that causes objects with mass to attract one another.
What is Gravity?
A phenomenon or process that involves multiple steps and repeats itself.
What is Cyclic Patterns?
A measure of how much matter is present in a substance
What is Mass?
To strike or hit something with any amount of force.
What is Collide?
Objects that affect one another
What are Interactiong Objects?
Having the tendency to pull other objects toward itself.
What is Attraction?
The shape of the illuminated portion of the Moon as seen by an observer, usually on Earth.
What is a Lunar Phase?
The change in an object’s position with respect to time and in comparison with the position of other objects used as reference points.
What is Motion?
Unit of measurement for force.
What is Newtons?
A straight path that an object can move along.
What is Direction?
The heaviness of an object; force of gravity on mass = weight.
What is Weight?
The imaginary line through Earth that extends from the North Pole to the South Pole and is the center of Earth’s rotation.
What is Axis?
The rate of change of position (or distance traveled) with respect to time.
What is Speed?
A tool that measures a pulling force by the tension on a spring in units of newtons.
What is a Spring Scale?
A change in motion caused by an unbalanced force acting on an object; includes increasing speed, decreasing speed, or a change in direction.
What is Acceleration?
A force that opposes the relative motion between two surfaces in contact
What is friction?
An obscuring of the light from a celestial body by the passage of an object between the celestial body and the observer or between the celestial body and its source of illumination.
What is an Eclipse?
Scientific law stating that energy can be neither created nor destroyed but just changes form.
What is the law of conservation?
Newton’s law stating that for every action force there is an equal and opposite reaction force; often referred to as Newton’s third law of motion.
What is Newton's Third Law of Action-Reaction?
A system that uses coordinates or background objects to establish position or to measure movement of a point in space.
What is Frame of Reference?
The path an object takes around another object due to gravitational force or a curved path followed by a satellite as it revolves around an object.
What is Orbit?
The slant of Earth’s axis, which is 23.5 degrees from vertical compared to Earth’s orbital plane around the Sun; results in the North Pole always pointing toward the North Star.
What is Tilt?
