May the force be with you
Force is measure in this.
What are Newtons or pounds?
5o Miles per hour North is an example of this vocab term.
What is Velocity?
A change in velocity with respect to time.
What is Acceleration?
A rubbing force that acts when two objects touch surfaces, and it always slows you down.
What is friction?
This is Mass times velocity. it is how hard it is to stop an object.
What is momentum?
Your sister is pulling a wagon. You help her and increase the force on the wagon. This will cause the wagon to do this.
What is speed up or accelerate?
A tire swing hanging from a rope on a tree remains completely motionless because these two forces are canceling each other out.
What is the rope hanging it up and the gravity pulling it down.
Speed and direction of an object.
What is Velocity?
Surfaces with less friction may also be called this.
What are smooth surfaces?
If an 8 pound bowling ball has the same velocity as a 12 pound bowling ball, which has more momentum?
The 12 pound bowling ball?
a force that attracts you based on your masses. keeping you together and pulling you down.
What is gravity?
Pulling a cake out of an oven is an example of a force because this is happening?
You are exerting force on it to move it.
Location of an Object.
What is position?
This is a situation where you might need more friction.
Answers vary.
This is an objects tendency to stay in motion, or stay at rest.
What is inertia?
A collection of forces on an object that causes a change in motion is this.
what is an unbalanced force?
An object at rest tends to stay at rest unless acted upon by this?
what is an unbalanced force?
A change in an objects position over time?
What is motion?
There is too much friction on the students slide. They reduce the friction by doing this?
Answers vary?
A pop cap and a quarter slide down the same ramp. The quarter traveled 66 cm and the pop cap slide 77 cm. This object experienced more friction.
What is the quarter?
Mr. Wall is playing tug of war with his students. Mr. wall exerts 125 N of force West. Mr. Wall's class exerts 225 N East. What is the net force of the rope? (include direction!)
What is 100 N East?
What are the fantastic four ways a force can change the motion of an object.
Stop, start, change speed, change direction.
A group of objects from which position and motion are measured.
What is Frame of Reference?
Aside form friction, this force is also slowing you down, especially in the air.
What is drag?
if the 8 pound bowling ball is going 20 mph and the 12 pound bowling ball is going 13 mph, which ball has more momentum?
What is the 8 pound bowling ball?
