Vocabulary
The measure of the strength of a force, named after Sir Issac Newton.
Newton
Name and explain 2 type of frictional forces.
Fluid, Static, Rolling, or Sliding friction
What is the 2nd Law of Motion?
An object's acceleration depends on the net force acting upon it.
What is the Law of Universal Gravitation?
The force of gravitation works admist all objcts that have mass.
Mass x Acceleration
Net force
A type of friction that occurs when a solid object moves through a fluid.
Fluid Friction
Name and explain 2 frictional forces.
Fluid, Rolling, Static, or Sliding friction
What is Newton's 1st Law of Motion?
Any object in motion tends to stay in motion unless acted upon by outside forces. (interia)
A force of friction that acts between two unmoving objects/objects at rest.
Static Frictional Force.
Mass x Velocity
Momentum
Resistance to change in motion.
Interia
What is the difference between weight and mass?
Weight is the measurement of the gravity on an object, while mass is how much mater is an object.
What is Newton's 3rd Law of Motion?
Every action has an equal and opposite reaction.
What is the Law of Conservation of Momentum?
In the absence of outside forces, the total momentum of objects that interact does not change.
Net force / (divided by) Mass
Acceleration
A characteristic of a moving object that is decided by the mass and velocity of the object.
Momentum
What are two ways you can increase the frictional force between 2 objects.
By changing texture, and how hard the objecs are pushed together
Name an example of Newton's 1st Law of Motion.
Moving forward in your seat after coming to a sudden stop.
When an object falls, he only force acting upon it/force causing it's acceleration is gravity
Free Fall
Net Force = 4 Kg m/s2
Satellites
What inflences the gravitational pull between 2 objects?
Name an example of Newton's 2nd Law of Motion.
A full shopping cart has less acceleration than an empty oneand is easier to push, and the shopping cart can go faster if pushed with more force.
A force that causes an object to move in a circular path.
Centripetal Force.
In a sad game of tug-of-war,you pull on the rope with a force of 100N to the right, and your friend pulls on the rope with a force of 100N to the left. What is the net force of the rope. (Hint: To the right is positive, while to the left is negative)
Net force = 0N
