A rabbit moved a distance of 10 meters in 2 seconds, how fast was the rabbit moving?
5 m/s
10 meters/2 seconds= 5 m/s
A man walked with a speed of 10 m/s for 60 seconds, how far did he walk?
600 meters
Distance = speed x time
= 10 m/s x 60 s
= 600 meters
If someone is traveled with a speed of 10 m/s and a distance of 20m, what is the amount of time that passed?
2 seconds
time= distance/speed
= 20m/10 m/s
= 2 seconds
an object's change in position relative to a reference point is _____
Motion
What does the prefix "osteo" mean?
Ex: osteoarthritis, osteoblast
Bone
A car drove a distance of 100 miles in 4 hours, how fast did the car drive?
25 m/h
100 miles/4 hours= 25 m/h
Name a unit of distance
Answers will vary:
Meters, Kilometers, miles, inch, cm, mm, yard etc
What is a unit of time? Name one
Answers will vary
second, minute, hour, day, week, year, century, millisecond etc
The force exerted on an object's mass by gravity is ____
Weight
What slows down the motion of objects on earth?
friction
If I say that a car has a velocity of 233 mph north, what is the speed of the car?
233 mph
Velocity is speed but also describes the object direction (in this case north)
What is the difference between a desk that is 12m long, and a desk that is 15m long?
3m
15 meters - 12 meters = 3 meters
Given that a ball traveled 50 meters to hit the ground, with a speed of 10 m/s. How long was the ball falling?
5 seconds
time= distance/speed
50 m/ 10 m/s = 5 seconds
What causes motion?
a. Unbalanced forces
b. Balanced forces
c. neither
a. Unbalanced forces
What is a force?
A push or a pull
Calculate the speed given a distance of 100m and a time of 5s.
20 m/s
100 m/5 s = 20 m/s
A man walked from his house to his car. He walked with a speed of 6m/s, and it took him 2 seconds to get to his car. How far is the car?
12 meters
6 m/s x 2 s= 12 meters
A man traveled a distance of 40 meters, they went at a speed of 2m/s. How long did it take them to travel this distance?
20 seconds
time= distance/speed
40 meters/2 m/s= 20 seconds
_______ is the rate at which velocity changes over time; an object accelerates if its speed, direction, or both change
acceleration
spelling doesn't count
What is the formula for Force?
Hint: newton's second law of motion
Force = Mass x Acceleration
