Lesson 10-17 (Force And Motion) Flashcards
When Does An Object Move?
When An Unbalanced Force Acts On it.
What happens when you apply force in the opposite direction of the objects motion?
You can slow down and stop the object
What happens when you apply force to an objects same direction?
You can increase the speed of the objects motion
Can two unbalanced forces cause things to move?
yes, the object will move in the direction of the larger force
What can help you with the patterns of motion?
Helps you predict the position,speed,and direction
What happens when an objects net force is 0?
forces are unbalanced and the objects motion does not change
What happens when the objects net force is any other value than 0?
the objects motion changes
What happens 2 forces act on each opposite direction of the object?
The net force is the difference(Subtract) between the two forces
True or false: The direction of the net force is the direction of the stronger force
true
True or false: Objects with greater mass has greater force
True
What equation can you use to calculate velocity?
Velocity (v) = distance (d) ÷ time (t)
True or False: Objects with a greater acceleration have greater force.
true
What can you use to calculate force?
Force (F) = Mass (m) × Acceleration (a)
What is Inertia?
Inertia is the tendency to resist change in motion.
True or False: More force is needed to change the motion of a heavy and fast moving object than a lightweight and slow moving object because it has more momentum.
True
