It's Natural
The study of the natural laws of the universe.
What is Physics
This is one of the most important concepts in all of physics.
What is All Motion is Relative
A physical measurement that contains both magnitude (number) and directional information.
What is Vector Quantity
How quickly an object moves in relation to a reference point.
DAILY SINGLE
What is Speed
The time rate of change of an object's velocity.
What is Acceleration
If a person walks 6 miles east then turns around and walks 2 miles west, what is their total displacement?
What is 4 miles east?
What is the acceleration of an object that moves with a constant velocity?
What is zero?
This science analyzes weather fronts, winds, humidity, cloud cover, etc.
What is Meteorology
He listed the presence of motion as one of his five arguments for the existence of God.
Who is Saint Thomas Aquinas
A physical measurement that contains only magnitude (number) and does not contain directional information.
What is Scalar Quantity
Two ways to express the speed of an object
What are average and instantaneous speed?
Can either speed up or slow down an object, depending on its direction.
What is Acceleration
On a distance-time graph for acceleration, a flat horizontal line shows this.
Answer pg 215
What is constant speed?
A rabbit is running east at 5.4 m/s and an eagle is pursuing at 4.4m/s. What is the relative velocity of predator and prey?
What is 1.0 m/s?
5.4m/s - 4.4m/s=1.0m/s
Defined as a change in position
What is Motion
This refers to using a reference point to detect motion.
What is a Frame of Reference
the equation for speed
What is distance/time or v=d/t
Is used to estimate values that are either higher or lower than the actual data collected.
What is Extrapolation
When an object is speeding up, the acceleration is in the same direction as the velocity.
What is Positive Acceleration
The ratio of the total distance traveled to the total time of the trip.
What is average speed?
A car traveled 80 km in 1 hr, 90 km the next hour and 110 km in the next 2 hours before arriving to their destination. This was the car's average speed.
What is 70 km/h?
80km + 90km + 110km=280km
1 hour +1 hour + 2 hours = 4 hours
280 divided by 4 = 70 km/h
These investigate the laws that govern space, time, forces, motion, matter, and energy.
DAILY DOUBLE
What are Physicists
The distance an object travels plus the direction from the starting point.
What is Displacement
Tells you how quickly and in what direction an object is moving in relation to a reference point.
What is Velocity
The slope of a line on a distance-time graph.
What is speed?
When an object is slowing down then its acceleration vector is directed in the opposite direction as its motion.
What is Negative Acceleration
The SI unit of speed is measured in this.
What is meters per second?
How many miles per hour does a car travel if it makes a 40-mile trip in 30 minutes?
What is 80 mi/h
30 mins = .5h
40mi divided by .5 hr = 80 mi/h
The branch of physics that deals with analyzing and understanding objects in motion, the forces applied to those objects, and the energy that exists in them.
What is The Science of Mechanics
A point agains which direction is measured.
What is Reference Point
The length of a path between two points.
What two or more bodies moving with same speeds are considered.
What is Relative Speed
True or False: An object can have constant speed and STILL have acceleration.
DAILY TRIPLE
TRUE
Acceleration on a distance-time graph is indicated by this.
What is a curved line?
What is the velocity of a bicycle in m/s if it travels 1km west in 4 mins?
What is 4.17 m/s west?
4min = 240 seconds
1 km= 1000 m
1000m divided by 240 = 4.17 m/s west
