The table provides information on various objects in our solar system.
Based on the information on the table, which object is an inner planet?
(a)
The table provides information on various objects in our solar system.
Based on the information on the table, which object is an outer planet?
(a)
The table provides information on various objects in our solar system.
Based on the information on the table, which object is a comet?
(a)
Why do planets orbit the Sun?

What is a balanced force?
When two forces acting on an object are equal in force but act in opposite directions (not moving)
An unopposed force that causes a change in motion (moving)
Select ALL of the examples of a balanced force:
A book sitting on a table
A dog running
A stretched rubber band (before it is released)
You walking to class.
What is an unbalanced force?
When two forces acting on an object are equal in force but act in opposite directions (not moving)
An unopposed force that causes a change in motion (moving)
Select ALL of the examples of an ubalanced force:
A book falling off of a table
A dog running
A rubber band flying through the air
You sitting in class
What is the difference between potential & kinetic energy?
SELECT ALL THAT ARE CORRECT.
Potential energy is stored up energy
Potential energy is energy of motion
Kinetic energy is energy of motion
Kinetic energy is stored up energy
How are potential & kinetic energy similar?
SELECT ALL THAT ARE CORRECT.
they can change (transform) back and forth from one type to another
they are exactly the same
they are measured in Joules
both are a type of energy
As potential energy is increases, what happens to the kinetic energy of an object?
(Imagine a roller coaster reaching the top of the highest hill *the very top* before it goes down)
As potential energy increases, its kinetic energy decreases
As potential energy increases, its kinetic energy also increases
nothing happens to its kinetic energy
As kinetic energy increases, what happens to the potential energy of an object?
(Imagine a roller coaster speeding down the biggest hill *the fastest point* )
nothing happens to its potential energy
As kinetic energy increases, its potential energy also increases
As kinetic energy increases, its potential energy decreases
What is the amount of kinetic energy the pendulum had at Position 2?
*you will need to subtract total energy - potential energy
(a)
How could you increase the potential energy of the marble in the picture?
by adding more books (to increase the height)
by making the ruler longer
you can't.
what is the formula to calculate speed?
speed = distance ÷ time
speed = time ÷ distance
speed = distance + time
