What is Distance/Time = Speed?
This is the formula for speed.

What is free fall?
In outer space since there is no air resistance and objects are only under the influence of gravity. This is called _______.

100

What is two surfaces rub together?
Friction occurs when ___________.

100

What is unbalanced?
In tug of war, the stronger team always wins because the forces are __________________.

100

What is move, fall, accelerate, create force etc.?
Newton created his laws by watching objects ____________________.

200

What is direction?
This is the major difference between speed & velocity.

200

What is 9.8 or 10?
Gravity on Earth causes all objects to fall at ________ m/s/s.

200

What is sliding?
An snowboarder uses ________________ friction to get from the top to the bottom of a mountain.

200

What is balanced?
When gravity and air resistance allow a falling object to reach terminal velocity, then these two forces are _______________________.

200

What is the Third Law?
As you push the buttons on a keyboard you are using which law of motion?

300

What is velocity?
Acceleration is the change in ____________.

300

What is mass of the objects and distance between them?
The force of gravity is affected by ___________ and _________.

300

What is static?
I cannot move my cabinet because it has too much ________________ friction.

300

What is increase?
Air resistance will ____________ as objects fall faster.

300

What is inertia?
As you slide down a hill in the snow, gravity is the force that keeps you moving. You have _______ unless you are acted on by an outside force like a tree!

400

What is speeding up, slowing down, or changing direction?
These are the three types of acceleration.

400

What is Jupiter?
This is the largest planet; therefore, it has the greatest gravitational force!

400

What is rolling?
Anything that is round can use this type of friction.

400

What is air resistance?
In a vacuum a feather and a stone will fall at the same rate. This is because there is no ____________________.

400

What is the bat is the action force and the ball changing direction is the reaction?
When Babe Ruth hit a homerun, what were the action and reaction forces at work?

500

What is an upward slope for positive acceleration and a downward slope for negative acceleration.
On a graph, this is how you tell the difference between positive and negative acceleration.

500

What is mercury because it is the closest to the sun?
Which planet do you think is affected by the sun's gravitational pull the most? Hint: think distance.

500

What is walking?
Without friction ____________ would be extremely difficult for everyone to do.

500

Who is Gallileo?
In the 1600s a scientist by the name of ____________ studied falling objects by rolling objects down an inclined plane.

500

What is... The law of inertia says that any object in motion or at rest will stay in that state until acted on by an unbalanced force. The 2nd law uses f=m x a to describe the relationship between the amount of force needed to accelerate a certain mass. The third law explains that all forces act in equal and opposite pairs.
Explain all three of Newton's Laws.
