Worksheet time: 10mins
When plates on Earth's surface slide over each other, there is force exerted. This causes
tropical cyclones.
tremors.
flood.
avalanche.
Tsunami can be triggered by earthquakes and underwater volcanic eruptions. When the powerful waves hit the shore,
coastlines will be eroded.
poisonous gas and ash are formed.
caves will be created.
it causes strong winds to exert great force.
Which statement on friction is false?
It is an example of a contact force.
It opposes motion between two surfaces.
It acts on stretched objects.
It prevents things from falling when we hold them.
What would happen is a north pole of a magnet came close to a north pole of another magnet?
they would be attracted to each other
they would be repelled from each other
All metals are attracted to magnets
True
False

Levitates from the same magnet poles
Levitates from opposite magnet poles
BONUS: How high does the Maglev train levitate above the track?
30-100 centimeters
1-10 centimeters
10-20 centimeters
It doesn't levitate
how much matter is present in an object
how much weight is present in an object
the amount a spring is compressed on a scale
how much matter is around the object
Why do we have a stronger gravitational attraction with Earth than the Sun?
the Sun has a larger mass
the Earth has a larger mass
we are closer to center of Sun
we are closer to center of Earth
BONUS: Jupiter has about 317 times more mass than Earth.
What can you infer from this fact?
That Jupiter’s gravitational force is much weaker than on Earth’s gravitational force.
That Jupiter’s gravitational force is much stronger than Earth’s gravitational force.
That Jupiter’s and Earth’s gravitational forces are equal.
Mass has no effect on the gravitational force between two objects
BONUS: What is the frictional force that objects experience as they move through the air?
gravity
air resistance
buoyancy
