Friction
What is friction?
A force that opposes the motion of an object.
What is force?
A push or a pull between objects.
What is inertia?
An object's tendency to resist change in motion.
When you are rolling a 12 pound ball down a hill, how does it show Newtons 2nd law?
Force=mass*acceleration.
What is a lab that we did that describe Newtons 3rd law?
When we were using the fan car.
On ice or slippery floor, the friction is less or more?
less.
What is an example of force pairs?
A baseball bat and a baseball.
What is Newton's 1st law?
If the forces on an object are balanced, the object will stay at rest or continue moving in the same direction at the same speed.
What is Newtons 2nd law?
The acceleration of an object is equal to the net force on the object divided by the objects mass.
What is Newtons 3rd law?
When one object pushes on another, the second object pushes back on the first with an equal and oppositely directed force.
What is friction?
Friction is a force that resists motion when objects move against another.
What is force pairs?
An action force and the reaction force that it produces, according to Newtons third law of motion.
What is an example of Newtons 1st law?
A ball rolling on the ground or floor.
When you are riding your bike New tons 2nd law comes into play because.....?
Because you are accelerating (gaining speed)
What is an example of Newtons 3rd law?
Rockets move forward by expelling gas backward at a high velocity.
What is kinetic energy?
Energy associated with moving objects.
What is net force?
The sum of all forces acting on an object.
What is an example of Newtons 1st law?
Brakes in a car.
In your own words describe Newtons 2nd law.
The acceleration of an object is directly related to the net force and inversely related to its mass.
What is an example of Newtons 3rd law?
When you are bowling and the bowling ball hits the pins.
What is an example of friction?
When we walk on the ground or floor.
What is an example of force?
Weight force (i.e. the weight of something)
How would you describe inertia?
Every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
What is an example of Newtons 2nd law?
Riding your bike.
In your own words describe Newtons 3rd law.
conservation of momentum.
