Force
If a heavier object hits a lighter object in motion than the lighter object will...
A) Change direction
B) Stop moving
C) Go faster
A) Change direction
What is the definition of force?
A push or a pull that can change the motion of an object.
What is the definition of infer?
To reach a conclusion using evidence and reasoning
Understanding a _____ relationship can help you infer what led to a particular result.
Cause and effect
If two objects with the same amount of mass hit each other while in motion, then which object will change direction?
A) they will both go in the opposite direction
B) the one that is on the left
A) they will both go in the opposite direction
What is the definition of Exert?
To apply force
what is the definition of mass?
The amount of matter that makes up an object.
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
If an object is in motion, and another object hits it from behind, the object will...
A) Slow down
B) Speed up
C) Change direction
B) Speed up
What is the definition of cause?

Velocity
If two objects with different masses both have a force applied to it, which object will move faster?
The lighter object will move faster.
If a ball is in motion and hits a wall, the ball will...
A) Go through the wall
B) stop
C) change direction
C) change direction
What is the definition of effect?
A result or change that happens because of an event or process.
How an object changes velocity depends on the ____ of the force exerted on that object.
Direction.
If two objects with different masses both have a force applied to it, which object will move slower?
the heavier object will move slower.
Why do objects with less mass faster than objects will more mass even if they had the same force?
A) Because the lighter an object is, the fast it will go
B) Because the lighter object had a stronger force
C) Because of luck
A) Because the lighter an object is, the fast it will go
