|---|---|---|---|---|
|
What is net force?
The combination of all forces acting on an object.
|
What is velocity?
The speed and direction of a moving object.
|
What is Newton's 3rd Law?
It states that for every action, there will be an equal and opposite reaction.
|
What is a contact force?
A force exerted on an object with direct contact.
|
What is 10 N + 50 N?
60 N.
|
|
What is inertia?
The force that allows an object to stay at rest or remain in motion.
|
What is acceleration?
The measure in change of velocity in a period of time.
|
What is a force pair?
An action and reaction force.
|
What is an unbalanced force?
When one force is pushing on another force with a different weight.
|
If one force equals 300 N, and one force equals 300 N, what is the total net force?
600 N.
|
|
What is Newton's 1st Law?
It states that an object in motion will stay in motion and an object at rest will stay at rest unless acted on by an unbalanced force.
|
What is Newton's 2nd Law?
It states that acceleration is the change of velocity of an object in motion overtime.
|
What is momentum?
The measure of how hard it is to stop a moving object.
|
What changes when the speed and direction of an object changes?
The acceleration changes. Speeding up, slowing down, and turning a different direction are all examples of changing acceleration.
|
When two forces are acting on an object with different weights, are they balanced or unbalanced?
Unbalanced.
|
|
What is friction?
The force that slows an object from its motion.
|
What is the formula for force?
F = m * a.
|
Fill in the blanks: For every action, there is an ______ and _______ reaction.
equal, opposite.
|
What is centripetal force?
A force that acts perpendicular to the direction of of motion, towards the center.
|
What is the correct formula for acceleration?
Force divided by mass equals acceleration.
|
|
If someone is pushing on a box on the left with a net force of 100 N, and someone else is pushing on the box on the right with a net force of 120 N, are the forces balanced or unbalanced?
Unbalanced. The person on the right has a heavier push of 20 N.
|
What is the net force when all forces acting on an object are balanced?
0 N.
|
What is a real-world example of Newton's 3rd Law?
A swimmer swimming, Newton's Cradle, a push or pull.
|
What is velocity?
The speed and direction of a moving object.
|
What is force?
Any push or pull exerted on an object.
