Vocabulary
Speed in a particular direction.
What's the definition of velocity?
A force between an object and the surface it is moving over.
What's the definition of friction?
A force is required to change the velocity of an object.
What is required to change the velocity of an object?
When two objects collide a force is exerted in opposite directions, but they are the same stregnth.
What happens when two objects collide?
A push or a pull that can change the motion of an object.
What's the definition of force?
To reach a conclusion using evidence and reasoning.
What's the definition of infer?
How an object changes velocity depends on the direction of the force exerted on that object.
How does an object change velocity?
Even though the force is exerted on eac object in a collision is the same stregnth, if the objects have different masses, thier changes in velocity will be different.
When does two objects have changes in velocity?
To apply a force
What's the definition of exert?
The amount of matter that makes up an object.
Whats mass?
A stronger force can cause a greater change in velocity.
What can a stronger force cause?
An event process that leads to a result or change
What's a cause?
The moment when two objects hit each other.
What's a collision?
Understanding a cause-and-effect relationship can help you infer what led to a particular result.
What can a cause-and-effect help you with?
A result or change that happens because of an event or process.
What's the definition of effect?
If the same strength force is exerted on two objects but the object with less mass will have greater chance in velocity.
When does an object with less masshave a greater change in velocity?
