A force that holds objects down toward the ground.
What is gravity?
100
A force that opposes motion between two surfaces that are in contact.
What is friction?
100
The distance traveled divided by the time interval during which the motion occured
What is speed?
100
the speed of an object in a particular direction.
What is velocity?
200
A balance beam measures mass in this unit.
What is a gram.
200
All objects in the universe attract each other through gravitational force.
What is the law of universal gravitation?
200
Kinetic and Static friction.
What are the two types of friction?
200
Velocity must include a reference direction. Speed is based on how fast you are going.
What is the difference between speed and velocity?
200
Velocity must include a reference direction. Speed is based on how fast you are going.
What is the difference between speed and velocity?
300
A persons mass changes on the moon.
What is false.
300
The force between objects don't always attract each other.
What is false
300
A force is applied to the object does not move
What is Static Fiction?
300
The formula of speed is distance divided by time= average speed.
What is speed formula
300
15 m/s east +1 m/s east =16 m/s east or 15 m/s east - 1 m/s west = 14 m/s east.
What is the velocity formula?
400
This force increases as mass increases.
What is the gravitational force.
400
This is due to friction.
Why the objects stop in the ground?
400
Kinetic friction means moving and static friction means not moving.
What is the difference between kinetic friction and static friction?
400
Solve this problem:
Kobe drove during two hours.He drove 160 km. What is the his average speed?
80m/s
400
Solve This Problem
18 m/s east + 3 m/s east
21 m/s east
500
Mass and weight are exactly the same.
What is false.
500
This scientist explained the Law of Gravity.
Who is Sir Issac Newton.
500
An example for static is a tables because tables are supposed to be stationary. An example for kinetic fiction is a car moving because cars need to move for transportation.
Give one example for static and kinetic friction.(explain)
500
You need this to figure out acceleration.
What is speed.
500
They are both equal speed.
How are velocity and acceleration related?
