  • What is a meteor?
    A streak of light is seen when meteoroid enter Earth's atmosphere.
  • How are tides on Earth affected by the Moon?
    The Moons gravitational pull causes tides on Earth
  • What is a comet
    chunk of ice and rock that releases gases as it orbits the sun
  • Name the planets IN ORDER
    Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
  • what two things causes seasons
    Earth's revolution and it's tilt
  • What is a Meteroid?
    a rock or metallic fragment of an asteroid that travels through space.
  • According to Newton’s Third Law, what happens when you push on a wall?
    The wall is pushing back you with an equal amount of force
  • Name the INNER planets
    Mercury, Venus, Earth and Mars
  • What causes day and night on Earth?
    Earth's rotation on it's axis
  • When identifying seasons, which season do you locate first?
    Summer
  • What is the formula to calculate speed?
    speed= distance / time
  • What is the difference between speed and velocity?
    Speed is how fast/slow an object is moving. Velocity is the speed and the direction the object is going.
  • A book is resting on a table with gravity pulling it down with a force of 10 N, and the table pushing up with a force of 10 N. What is the net force acting on the book?
    0 N
  • If two people are pushing a box in opposite directions with forces of 50 N to the right and 30 N to the left?
    Is this balanced or unbalance?
  • Where is the Kuiper Belt located?
    Beyond the orbit of neptune
  • How does friction affect the motion of a car on a road?
    Friction between the tires and the road helps the car slow down
  • What are the 3 conditions Earth has to sustain life?
    Proximity to the sun, presence of water, and composition of the atmosphere
  • When identifying season, which direction do you go after identifying summer
    counter-clockwise
  • On a distance-time graph, how can you tell if an object is moving at a constant speed?
    If it is a straight diagonal line
  • Name the OUTER planets
    Jupiter, Saturn, Uranus, and Neptune
  • If two people are pushing a box in opposite directions with forces of 50 N to the right and 30 N to the left, what is the net force on the box and which direction would the box move?
    20 N to the right
  • What is the difference between potential energy and kinetic energy?
    Potential energy is stored energy, while kinetic energy is energy in motion
  • What is a meteorite?
    a meteor fragment that hits Earth
  • How do the inner planets differ from the outer planets in our solar system?
    The inner planets are rocky and small. The outer planets are larger and gaseous
  • How many tides happen in a day
    4
  • What is an asteroid and where are they located?
    a rock in orbit between Mars and Jupiter that orbits the sun.
  • A car travels 120 kilometers in 2 hours. What is the car's average speed?
    60 km/h
