Gravity
One object has a mass of 5 another objects has a mass of 3.
What is the force of gravitational attraction between the two objects?
15 units
What is the word that refers to the tendency of an object to resist a change in motion?
Inertia
If you bring two north poles of magnets close together what happens?
They repel
Earths lithosphere is made up of what layers of the Earth?
The crust and the upper mantle. Plate tectonics are made up of the lithosphere.
Which front usually brings short, heavy rain or thunderstorms?
Cold front
The gravitational attraction between two objects is 45.
The mass of object X is 9 what is the mass of object Y?
5 units
Which Newton’s law explains why seatbelts are important?
First Law
An object in motion will stay in motion unless acted upon by an outside force, and an object at rest will stay at rest unless acted upon by outside force.
What is an example of static electricity in nature?
Lightning
Earthquakes occur along what type of plate boundary?
Transform Boundary
Which front usually brings steady, light rain over a long period of time?
Warm front
Assume that the force of gravitational attraction between two objects is 8 units.
What will the force of gravitational attraction between the objects be if the mass of both objects doubles?
32 units
Which law explains how swimming works?
The third law. For every action there is an equal and opposite reaction.
Static electricity and the shock that you may feel has to do with the movement of what subatomic particles?
Electrons
Which tool do scientists use to study plate movement?
Seismograph
What type of front forms when two air masses meet but neither moves?
Stationary front
Assume that the force of gravitational attraction between two objects is 24 units.
What will the force of gravitational attraction between the objects be if the distance between the objects doubles?
6 units
A 4 kg object accelerates at 3 m/s². What is the force?
12 N
What is static discharge?
The quick movement of electrons from one object to another in order to restore balance
What way do plates move at a convergent plate boundary and what might they form?
They move together. This may form Mountains, or deep ocean trenches.
How do scientists use weather balloons to explore Earth's atmosphere?
To measure wind speed and direction
Assume the force of gravitational attraction between two objects is 18 units.
What will the force of gravitational attraction between the objects be if the mass of each object doubles and the distance between the two objects doubles?
18 units
If a force of 10 N pushes a 2 kg object, what is the acceleration?
5 m/s2
F=M x A
A = F/ M
Why can you get a shock if you touch a metal doorknob after walking across a wool carpet?
You have lost electrons and the doorknob has many. The shock you feel is the electrons moving to restore balance.
Which way do plates move at a divergent boundary and what may form at this boundary?
Mid-ocean ridges, or rifts.
True or False: Cold fronts usually move faster than warm fronts.
Explain your answer.
True, because of pressure
