Define gravity

the pulling force of all masses towards each other. 

100

What is gravity's rate of acceleration?

9.8 m/s2

100

True or False:

Gravity acts with less force on the moon than the earth.

True, on the moon, gravity is about 1/6 of that on the earth. 

The moon's gravity acceleration formula is 1.6 m/s2 versus 9.8 m/s2 on earth.

Finish the phrase: An object at rest, will... 

remain at rest.

Mr. Segale, an Italian-American landlord, rented a warehouse to Ninitendo in the 1990's.  He was an unusual personality but gave Nintendo extra time to pay rent, which saved some of their projects. Which Nintendo characters did he inspire?

Mario, the plumber

200

Define acceleration 

speeding up.


It can include changing direction of movement and even negative acceleration (slowing/stopping).

200
Gravity's rate of acceleration is 9.8 m/s2

How quickly will a free falling object be traveling 2 seconds after it is dropped?

19.6 m/s2

200

(True or False) An rocket is flying at a constant speed of 30 m/s.  It is accelerating.

False

200

Finish the phrase:

An object in motion, will... 

remain in motion

Lara Croft is the main character of what videogame?

Tomb Raider

300

What is deceleration or negative acceleration?

slowing down or stopping.

300
What is the rate of acceleration of gravity on an object thrown straight upwards.

-9.8m/s2

Gravity's acceleration is constant.  If you are speeding going upwards, gravity is negative acceleration at the same rate.

300

True or False: 

Isaac Newton's complete works on Physics have not needed to be changed or updated since being written in the late 1600's.

False, Newton's works have been updated.  His ideas  still apply to typical motion.

However, Einstein's works on objects approaching the speed of light more accurately describe the universe.

String theory is being shown to improve on Einstein's work. However, 95% of the universe is made up of dark matter and dark energy and scientist are currently working to understand what these are.

Fill in the blank:


Every action has an equal and opposite _________. 

REACTION

This videogame that involves building your own world is the most purchased game of all time.

Minecraft

400

Speed in a certain direction

velocity

400

The distance formula for a free falling object is

Distance fallen= ( 9.8m/s2 *S2 )/ 2

How far will an object in free fall travel after 3 seconds

44.1 meters

400

True or false: a change in direction is a form of acceleration

True, acceleration is a change in speed or direction.

The same way you feel inertial forces when slowing down or speeding up, you also feel them when turning left or right in a car.

400

In Newton's Second Law, what does Mass X Acceleration equal?


Mass x Acceleration = _______ 

Force

Force= Mass x Acceleration

F= m a

400

Golden Eye was a classic video game on Nintendo 64 in the 1990s.  Who was its main character?

Bond, James Bond

500

The tendency of an object at rest to stay at rest and an object in motion to stay in motion.

Inertia

500

A catapult shoots a rock straight up at 20 m/s. After approximately how many seconds will it hit the ground?


Gravity is a constant acceleration of 9.8m/s2 or round to 10m/s2

4 seconds

500

True or false,

The following graph represents acceleration

True, the speed is increasing over time. 

500

Can you name all 3 of Newton's Laws of motion?

1. Objects at rest will remain at rest and objects in motion will remain in motion.

2. Force = mass x acceleration- describes forces required to accelerate objects.

3. Every action has an equal and opposite reaction.
