Define gravity
the pulling force of all masses towards each other.
What is gravity's rate of acceleration?
9.8 m/s2
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.

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
Define acceleration
speeding up.
It can include changing direction of movement and even negative acceleration (slowing/stopping).
19.6 m/s2
(True or False) An rocket is flying at a constant speed of 30 m/s. It is accelerating.
False
Finish the phrase:
An object in motion, will...
remain in motion
Lara Croft is the main character of what videogame?
Tomb Raider
What is deceleration or negative acceleration?
slowing down or stopping.
-9.8m/s2
Gravity's acceleration is constant. If you are speeding going upwards, gravity is negative acceleration at the same rate.
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.
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
Speed in a certain direction
velocity
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
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.
In Newton's Second Law, what does Mass X Acceleration equal?
Mass x Acceleration = _______
Force
Force= Mass x Acceleration
F= m a
Golden Eye was a classic video game on Nintendo 64 in the 1990s. Who was its main character?
Bond, James Bond
The tendency of an object at rest to stay at rest and an object in motion to stay in motion.
Inertia
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
True or false,
The following graph represents acceleration
True, the speed is increasing over time.
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.
