SVA and Newton's Laws
Factors that can cause an object’s acceleration to change.
What is change in speed and direction, or both?
For example, speeding up, slowing down, or turning causes acceleration.
How potential and kinetic energy relate to each other during the motion of a roller coaster.
What is as it moves down, potential energy converts to kinetic energy, increasing its speed?
How gravity influence the motion of objects on Earth and in space.
What is Gravity pulling objects toward Earth’s center, affecting falling objects and keeping planets and moons in orbit?
The direction everything moves in space.
What is counter clockwise?
The factors that make Earth a habitable planet compared to other planets in our solar system.
What is Earth has liquid water, a protective atmosphere, moderate temperatures, and a magnetic field, all of which support life?
Newton’s First Law says the motion of an object when no external forces are acting on it is this.
What is an object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by an external, UNBALANCED force?
The three main ways thermal energy can be transferred, and how they differ.
What is thermal energy transfers by conduction (direct contact), convection (fluid movement), and radiation (electromagnetic waves)?
How Earth’s tilt during its revolution around the Sun cause seasons.
What is Earth’s tilted axis means different hemispheres receive varying sunlight during revolution, causing seasons?
(direct and indirect sunlight)
The phases of the Moon repeat in a cycle approximately every 29.5 days.
What is the Moon completes one orbit around Earth approximately every 29.5 days, causing the phases to repeat in a cycle?
The four main Earth spheres, and how they interact with each other.
What are the geosphere (ground), hydrosphere (water), atmosphere (air), and biosphere (living things) and how they interact constantly?
The calculation of the acceleration of an object if you know its mass and the force used to move it.
What is acceleration = force/mass ?
Using the formula F=ma
How kinetic energy affected when an object’s speed increases.
What is Kinetic energy increases as the object’s speed increases?
How the motion of objects change if there were no gravity.
What is without gravity, objects would move in straight lines and not orbit; without inertia, objects would not continue moving without force?
Tide formed when the Sun, Earth, and Moon are in a straight line.
What is a Spring Tide?
How the Earth’s rotation and revolution differ, and the effects each have on our planet.
What are rotation, the Earth spinning on its axis causing day and night, and revolution, Earth orbiting the Sun causing the year and seasons?
How inertia explain why passengers lurch forward in a car when it suddenly stops.
What is passengers lurch forward because their bodies tend to keep moving forward due to inertia when the car suddenly stops?
How the transfer of thermal energy affect the temperature of objects involved.
What is thermal energy transfer causes the temperature of the warmer object to decrease and the cooler object to increase until they reach thermal equilibrium?
How Earth’s rotation and revolution differ, and the effects each have on our planet.
What is rotation is the Earth spinning on its axis causing day and night; revolution is the Earth orbiting the Sun causing the year and seasons?
This tide occurs with 1st Quarter and 3rd Quarter moon phases.
What is Neap Tide?
A plant absorbs C02 from the air and uses it for chemical energy, a process known as photosynthesis.
What are producers in the biosphere interacting with the atmosphere?
The difference between speed and velocity.
What is speed is a scalar quantity only and velocity is a vector quantity because it includes direction. (north, south, east, west).
Maximum kinetic energy of a roller coaster cart.
What is the cart at the bottom of a the lowest point of the track?
This best describes why the moon orbits the Earth.
What is the compromise of inertia and gravity?
Causes of the different phases of the Moon that we see from Earth.
What is moon phases are caused by the changing angles of sunlight hitting the Moon as it orbits Earth, showing different portions of its lit side?
This would happen if the Earth was too close to the Sun or too far away from the Sun.
What is Earth would not have liquid water?
