Velocity
Equation of velocity
What is..
velocity is equal to the change of distance divided by change of time.
Equation of acceleration.
What is...
acceleration = change of velocity divided by change of time.
What is.. Any push or pull on an object
For every action there is an equal and opposite reaction.
Newton's 3rd Law of Motion
What is the name of Miss Nelson's cat?
What is...

A train traveled 350 km in 2.5 hours. What was the average speed of the train?
ANSWER MUST BE IN METERS/ SECOND.
1 km= 1000 m
3600 seconds= 1 hour
What is..
350 km= 350,000 m
2.5 hours= 9,000 seconds
velocity = 350000/ 9000= 38.9 m/s
Approximately what is the acceleration due to gravity?
What is..
10 m/s2
If a person and a raft weighs 550 N, how much must the buoyant force on the raft be to keep them from sinking?
What is...
550 N
Newton's 2nd Law of Motion
What is...
Force is equal to mass times acceleration.
What type of mathematics did Isaac Newton need to create in order to make sense of the world around him?
What is...
Calculus

After 2.0 seconds, a students was riding her bike at 3.0 m/s on a straight path. After 5.0 seconds, she was moving at 5.4 m/s. What was her acceleration?
ANSWER SHOULD BE IN M/S2
What is..
a= v/t
a= (5.4m/s- 3 m/s) / (5s - 2s) = 0.8 m/s2
What does a "Vector" mean?
What is...
A force with both magnitude (Size) and direction.
Which law of motion did your balloon are demonstrate?
What is..
Newton's 3rd law of motion
What month is Miss Nelson's birthday?
What is..
June
A person leaves one city at 12 pm. They need to be in another city 186 km away at 3 pm. The speed limit the entire way is 65 km/h. Can they arrive at the second city in time? MUST SHOW YOUR WORK!
What is...
v=d/t
v= 186km/ 3 hours = 62km/ hr.
The speed limit allows them to drive 65 km/hr, so they WILL make it on time.

When a person is in a car accident, they tend to fly forward in their cars. This is why we have seat belts and air bags.
What law of motion explains why your body moves forward at a dangerous speed?
What is..
Newton's 1st law, the law of inertia.
Newton's full proper name.
What is...
Sir Isaac Newton
