Understanding a cause-and-effect relationship can help you infer what led to a particular result.
What direction do you apply a force to make an object that is not moving start moving?
Any direction.
Which surface has more friction; a smooth or rough surface?
The rough surface has more friction.
Something that leads to a result or change
What is cause?
The speed in one direction
What is velocity?
A _____ is required to change the velocity of an object.
A force is required to change the velocity of an object.
What direction do you apply a force to make an object that is already moving speed up?
What are the two types of forces?
Push and pull.
A change or result that happens because of something
What is effect?
The push or pull that is able to change the motion of an object
What is force?
A stronger force can cause a greater _______.
A stronger force can cause a greater velocity.
What direction do you apply a force to make an object that is already moving slow down?
Opposite direction that it is going.
What are the 5 ways an objects motion can change?
Speed Up, Slow Down, Change Directions, Start, and Stop.
To reach a conclusion by using evidence and reasoning
The force between an object and the surface underneath it
What is friction?
How an object changes velocity depends on the _________ of the force exerted on that object.
How an object changes velocity depends on the direction of the force exerted on that object.
What direction do you apply a force to make an object that is moving stop moving?
Opposite direction it is going.
If an object is moving to the right, which direction would you need to apply a force to make it slow down?
Left.
True or False: A less massive object will be more difficult to stop.
False.
The amount of matter that makes up something
What is mass?
If the same strength force is exerted on two objects but the objects have different masses, the object with ____ mass will have a greater change in _______.
If the same strength force is exerted on two objects but the objects have different masses, the object with less mass will have a greater change in velocity.
What direction do you apply a force to make an object that is already moving change directions?
Opposite direction it is going.
If two objects have the same strength exerted on them but one is heavier than the other, which will go faster?
The lighter object.
True or False: An object with a lighter mass will go faster than one with a heavier mass if the same force is applied.
True.
