This has the most friction out of rubber, ice, and plexiglass.
What is Rubber?
Out of these two vehicles will take more force to stop?
Dumptruck or a VW Bug
What is the dumptruck?
This is the amount of matter in an object.
What is mass?
Gio pushes a chair across the floor. It gradually slows down and stops. Gio is wondering why the chair stop moving?
friction from the floor ya goof
(Larger or smaller) objects are easier to stop when they are in motion
What is smaller
This is what is required to change the velocity of an object.
What is Force?
These are the 5 ways an object can move
What are: Start, Stop, Speed Up, Slow Down, or Change Direction
A push or pull that can cause motion
What is force?
Darron is playing pool. You hit the white ball and it hits a solid blue ball that is still. What happens to both balls after the collision?
The white ball will stop and the blue ball will start moving, and hopefully Darron makes the shot
This is the formula for speed.
What is distance/time?
To stop an object, the force must come from:
the opposite direction of the object's motion
If there are two objects, one with a mass of 15 kg, and one with 10 kg, and both are applied the same force, THIS object will go further.
What is the 10 kg object?
This is the force that slows down motion between touching objects.
What is friction?
Ms. Young decided to get a second job as a truck driver. She is wondering why the 18 wheeler takes more force to drive than her Subaru Forester. Who in this brilliant class can tell her why?
The 18 wheeler has a lot more mass than the Subaru Forester
To apply a force is the definition of this word.
What is exert?
To speed up an object, the direction of force should be:
in the same direction of the object's motion
A soccer ball, a baseball, and a bowling ball were all pushed with a force and had the same ending speed. Does this mean they had the same force applied to them?
No, they are different masses.
When 2 objects hit each other it is called this
What is a collision?
A pod hits a space station. The space station is much more massive than the pod. The pod experiences a much greater change in velocity. True/False
True
This is the only place that does not have (or has very little) friction
What is space?
Which direction does the force of Friction act on an object
The opposite direction
An object with less mass collides into an object with more mass. Which object will have the great change in velocity?
less mass
Speed in a particular direction is called this
There is a collision between a bug and a car. The bug experiences a greater change in velocity because...
it has a much smaller mass
This is why the pod failed to dock onto the space station.
The pod had a lot more asteroid samples, and it's mass was greater than normal, so the thruster force that is usually used was not strong enough to stop it.
