Newtons Laws
Newton's First Law states
An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an external force.
In other words, the law of inertia.
What happens to Force if acceleration increases?
Force increases as well. F=ma
What is displacement?
The distance an object moves away from its original point.
When a boulder is pushed down a slope, what type of friction takes force on the boulder?
Rolling friction.
What type of force is in effect when someone pushes a rock down a hill?
Contact Force.
Newton's Second Law states
Acceleration of an object is equal to the net force acting on it divided by the object’s mass. F = ma
Non-Contact
What is acceleration?
The rate at which an object's velocity changes over time, measuring how quickly it speeds up, slows down, or changes direction.
When a hockey puck is slid across ice, what type of friction occurs?
Sliding friction.
What type of force occurs when a magnet pulls another magnet towards itself?
Non-Contact
Newton's Third Law states
Newton's third law of motion states that for every action, there is an equal and opposite reaction.
What happens to Force if mass decreases.
Force decreases as well.
What is inertia?
The natural tendency of an object to resist changes in its state of motion.
When something is pushed across carpet, it is harder to move. What friction causes this?
Static friction.
Heads or Tails.
Tails.
When the equation Force=Mass*Acceleration is used, which of Newton's Laws is in effect?
Newton's Second Law
When static cling occurs, what type of force is taking place?
Non-contact force.
Double Jeopardy!
What is Floccinaucinihilipilification?
It is the action or habit of estimating something as worthless, trivial, or unimportant
A diver jumps off a board and lands into deep water. The force of the water stops diver from continuously falling. What friction is in effect here.
Fluid Friction.
Which of Newton's Laws state that for every action, there is an equal and opposite reaction.
Newton's Third Law
When a fan is spinning, and is then turned off, it continues to spin for a while even after it is turned off. Which of Newton's Laws comes into effect here?
Newton's First Law. (law of inertia)
1295 units.
What is terminal velocity?
The maximum velocity an object can reach.
Air resistance is what type of friction?
Fluid Friction, because it applies to both liquids and gases.
When an object is falling and the force of air resistance equals the force of gravity, what do we call this?
Terminal Velocity.
