Mass is a measure of the amount of matter in an option.
What is mass?
100
Speed is the distance traveled divided by the time interval during which the motion occured
What is speed?
100
Motion is an objects change in position relative to reference point
What is motion?
100
Friction is a force that opposes motion between two surfaces that are in contact
What is friction?
100
Gravity is a force of attraction between objects that is due to their masses
What is gravity?
200
One-sixth or 1/6
The gravitational force on the moon is about what fraction of the Earth's gravitational force?
200
The SI unit for speed is meters per second (m/s)
What is the SI unit for speed?
200
1666
When was motion discovered?
200
if the surface is rough or if the surface is smooth.
what 2 factors influence the amount of friction?
200
it is caused bu the uneven amount of mass and energy
What causes gravity?
300
weight
What other word means mass?
300
Average speed = Total distance (total distance divided by time) --------------- Total time
How do you determine average speed?
300
1686 the three laws were presented

300
The left direction
What direction does a friction force act on?
300
1666 they were developed
When was gravitation theories discovered?
400
Mass in an object does not change.
How much does an object's mass change?
400
Galileo
Who was the first person to measure as distance over time?
400
Acting on an object, will change its velocity by changing either its speed or its direction.
What does the second law of motion state?
400
1493
when was friction discovered?
400
by the rotation of the earth and the gravitational effects of the moon and sun
how are tides caused?
500
The gravitational force is about the same everywhere on Earth. So, the weight of any object is about the same everywhere.
How is the gravitational force related to the weight of an object?
