Calculate the average speed (in meters/sec) if a golf cart runs 140 meters in 10seconds.
140 meters / 10 seconds = 14m/s
What is the formula for time?
t = d/s
Describe the speed of the car.
The car is moving at a constant speed.
What is the formula for distance?
d = s x t
s= d/t
A bicycle rider travels 50.0 Km in 2.5 hours. What is the cyclist’saverage speed?
s = d/t. s= 50 km /2.5 hours = 20 km/hr
What is the average speed (in miles per hour) of the car that traveled a total of 200 miles in 5.5 hours.
s = d/t s= 200 miles / 5.5 hours = 36.36 m/hr
Describe the speed of the car.
The car moves at a constant speed before it stops. Then the car moves at a slow constant speed before it moved backwards at a fast constant speed.
____________________ energy depends on the objects relative position.
Potential Energy
Draw the Speed Triangle with everything included.
Calculate the average speed (in Km/hr) of Charlie who runs to the store 4 Km away in 30 minutes?
What is the definition of the word PER in speed problems?
It can mean devision or for every amount of a certain distance you will go a specific time.
Describe the speed of the car.
The car moved at a fast constant speed before moving backward at a constant speed then stopping. The car then moved forward again at a fast constant speed. Then it moves at an inconstant speed.
_______________ energy is the energy expelled when something is moving.
Kinetic Energy
Thermal energy depends on the __________________ of the object.
Mass
Mike rides his motorcycle with a constant speed of 56 miles per hour. How far can he travel in 105 minutes?
Which has more thermal energy a glacier or a bath tub of hot water.
Decribe the speed of all three cars.
A - is traveling at a constant speed.
B - Is traveling at a slow constant speed.
C - Is traveling at a slow constant speed, then it slows down at a constant speed. Then the car stops moving. Then it moves forward for a fast constant speed, then it slows down a bit but still moves forward at a constant speed.
_______________ is the measure of kinetic energy with a substance at any given instance.
Temperature
An ant can travel approximately 30 meters per minute. How many meters could an ant move in 45 minutes?
d = s x t d= 30 m/min x 45 min = 1,350 meters
Pete rides his motorcycle with a constant speed of 116 km/h. How far can he travel in 255 minutes?
How much time would it take for the sound of thunder to travel 2000 meters if sound travels at a speed of 330 meters per sec.
t = d/s t= 2000 m / 330 m/s = 6.06 seconds
Describe the motion of each graph.
A - The car is stopped
B - The car is moving at a constant speed.
C - The car is moving backward at a constant speed.
D - The car is not moving at a constant speed.
E - The car is not moving at a constant speed.
F - The car is moving at a slow constant speed.
____________________ energy is the total amount of kinetic energy within a substance. The amount of energy depends on the mass of the object.
Thermal
Describe how an igneous rock can become a sedimentary or metamorphic rock.
