A plane flying from Austin to Dallas
makes the 192 mile trip in 1 hour.
This is its velocity.
What is 192 miles/hour North?
Back to you Alex

The 3 ways that an object can
accelerate.
What are speed up, slow down, and
change direction?
Back to you Alex
300
The speed of the athlete in the graph
below
What is 10
meters per
second?
(s)
Back to you Alex
400
The section of the graph that
represents moving at a constant
velocity
What is
section a?
Back to you Alex
500
The definition of force.
What is a push or a pull?
Back to you Alex
100
You might add sand to an icy
driveway to increase the force of
this.
What is friction?
Back to you Alex
200
The type of forces acting on the box
below.
What are unbalanced forces?
5N

The definition of inertia
Daily Double
What is the tendency of an object to resist
change in its motion?
Back to you Alex
400
The more of this an object has, the
more inertia it will have.
What is mass?
Back to you Alex
500
Newton’s 2nd law says that force
equals this.
What is mass x acceleration?
Back to you Alex
100
Newton’s 1st law says this.
What is an object at rest will stay at rest,
and an object moving with a constant
velocity will continue moving with that
constant velocity, unless acted on by an
unbalanced force?
Back to you Alex
200
According to Newton’s 2nd law, in
order to increase the acceleration of
an object, you must do this.
What is increase the amount of force you
use OR decrease the mass of the object?
Back to you Alex
300
The law and explanation for why
we seem to lift out of our seat when
a rollercoaster car goes down a hill.
What is Newton’s 1st law because
our body is at rest at the top of the
hill and tends to want to stay at rest
until acted on by an unbalanced
force?
Back to you Alex
400
The law and explanation for why
when you hit a volleyball, the
volleyball flies away from you and
your hand stings.
What is Newton’s 3rd law
because you exert a force on the
volleyball (volleyball flies away)
and the volleyball exerts an equal
force on you (your hand stings)?
Back to you Alex
500
The force that you exert on the
machine.
What is input force?
Back to you Alex
100
The simple machine that is an
inclined plane wrapped around a
cylinder.
What is a screw?
Back to you Alex
200
The 3 ways that a simple machine
can make work easier.
What are decrease amount of input force
needed, spread the force out over a greater
distance, and change the direction of the
force?
Back to you Alex
300
Of the 3 ways machines can make
work easier, a 3rd class level makes
work easier by doing this.

What is multiplying your input force (or
decreasing the amount of force needed)?
3rd class lever

Back to you Alex

The type of pulley that you would
use if you wanted to decrease the
amount of force needed and change
the direction of the force.

Fixed Moveable Pulleys
What is a multiple
pulley system?

Stored energy.
What is potential energy?
Back to you Alex
100
The definition of kinetic energy.
What is energy of motion?
Back to you Alex
200
Of a skateboard, a ball, or a
person—the one that has the greatest
potential energy at the top of a
staircase.
What is a
person?
Back to you Alex

where the rollercoaster has the
greatest kinetic energy
