Name:_______________________ Date:______________
Period:_______ Formula Challenge
What do the following units represent?
Use D for distance, T for time, S for speed, A for acceleration, M for Momentum and N for Force
___ D 1. 14 km __ N_4. 6N __ S_7. 14 mph __ D_ 10. 1.4 m
__ S_ 2. 30 m/s ___ A5. 12 cm/s2 __ T_8. 3.2 sec __ A_ 11. 6 cm/min/sec
__ T_ 3. 34 min __ S _6. 150 mph __ A_9. 25 ft /s2 __ M_ 12. 3 g x m/s
Write how you know which formula to use?
SPEED MOMENTUM ACCELERATION
Speed or Velocity = Distance/Time Momentum = Mass X Velocity Acc= Final speed- Initial speed/time
Distance = Time X Velocity Mass = Momentum/Velocity
Time = Distance/Velocity Velocity = Momentum/Mass
Finish the density formula and write out all the possible ways it can be expressed (like the box above)
DENSITY
M
D=M/V
D V
Write the proper formula used to complete the problem:
Write DENSITY, SPEED, or MOMENTUM
1. Mass and velocity. 2. Velocity and Time. 3. Density and Mass
Formula? _ MOMENTUM Formula? _ SPEED __ Formula? DENSITY __
Practice Problems:
1. If Steve throws the football 50 meters in 3 seconds, what is the average speed (velocity) of the football?
Formula: Speed=Distance/Time 50m / 3s = 16.7 m/s
2. If it takes Ashley 3 seconds to run from the batters box to first base at an average speed (velocity) of 6.5 meters per second, what is the distance she covers in that time?
Formula: Speed=Distance/Time distance
6.5m/s = 3sec = 19.5m
3. Bart ran 5000 meters from the cops and an average speed (velocity) of 6 meters/second before he got caught. How long did he run?
Formula: Speed=Distance/Time 5000m
6 m/s = time = 833.3sec
4. What is the acceleration of an object that takes 20 sec to change from a speed of 200 m/s to 300 m/s?
Formula:
Acc= Final speed- Initial speed/time 300m/s-200m/s
Acc = 20sec = 5 m/s2
5. A car traveling south at a velocity of 30 m/sec slows down to a velocity of 10 m/sec in 10 sec. Calculate the deceleration.
Formula: Acc= Final speed- Initial speed/time
10m/s – 30 m/s
Acc = 10 sec = -2.0 m/s2
Newton’s Second Law
Force = Mass X Acceleration for example: 1 Newton = 1Kg X 1 m/s2
Weight = Mass X Gravity
Mass = Force/Acceleration
Acceleration = Force/Mass
6. A force of 20 N acts upon a 5 kg block. Calculate the acceleration of gravity on the object.
Formula: Force = Mass X Acceleration or Acceleration = Force/Mass
20N = 5kg X Acc or Acc = 20N / 5kg = 4m/s2
7. A force of 200 N is exerted on an object mass of 40 kg that is located on a sheet of perfectly smooth ice.
Calculate the Acceleration of gravity:
Formula: Force = Mass X Acceleration or Acceleration = Force/Mass
200N = 40kg X Acc or Acc = 200N / 40kg = 50m/s2
Which Law can be used to describe the situation:
Write ONE, TWO, or THREE
1. The relationship between an objects mass, its acceleration and its force: TWO
2. For every action there is an equal and opposite reaction: THREE
3. Every object in motion tends to stay in motion unless another force is acted on it: ONE
4. Inertia: ONE
5. Shooting a rocket into space: THREE
6. Your weight is:
a. actually your mass c. the gravitational attraction between your body and the earth
b. never changing d. measured in killiliters
7. Jupiter has three times the gravitational force of Earth.
So on Jupiter, a 100kg object would have a mass of? The Mass would stay the same, so 100kg
8. An object is pulled northward at 20N and southward at 15N.
What is the direction and force of the object? 5N northward
