law act 1, friction, and force
what was the first newton law
object in motion will stay in motion object i rest will stay in rest
what was the second law of motion?
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object
what was the third law
A force is a push or a pull that acts upon an object as a results of its interaction with another object. Forces result from interactions!
what is speed and how does it move
the speed is how much force in potential is in kinetic energy. It is also the rate of motion.
what is time and distance
Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present,
Distance is the total movement of an object without any regard to direction.
who made newton laws
Sir Isaac Newton made newton laws hmiself.
If the car was pushed down the hill with more force, what will happened if the car was going down the hill? Use the acceleration to demonstrate the car.
If the car was pushed down the hill, the acceleration will decrease.
An ostrich runs up the hill with a constant speed at the distance at 43 miles per hour. At the top of the hill, he stops running and took a break for 10 minutes and went down the hill at 10 mph and came back home. Find the acceleration and distance of the ostrich.
The ostrich's acceleration and speed increase because, he starts running. The ostrich's speed decreases for running down the hill at the distance and time.
What is motion?
The object's change in position relative to a reference point.
What stops time but has a very close distance?
The distance for you never changes because you're not moving.
What did newton make the laws for?
Far more than just discovering the laws of gravity, Sir Isaac Newton was also responsible for working out many of the principles of visible light and the laws of motion, and contributing to calculus.
Why was the newton laws made?
He developed his three laws in order to explain why the orbits of the planets are ellipses rather than circles, at which he succeeded, but it turned out that he explained much more. The series of events from Copernicus to Newton is known collectively as the Scientific Revolution.
What is Mass?
Name an example about mass.
A measure of the amount of matter in an object.
An example of mass is like a bowling ball has more mass than a basketball. Also, greater masses have attraction between in two.
why does speed matter
speed matters because we have potetial and kinetic energy
What is inertia?
The tendency of all objects to resist a change in motion.
Which is a form of decreasing friction Intentionaly?
What will happen if you put balloon on your hair and what causes friction?
Oil on a squeaky door hinge.
If you put the balloon on your hair, it causes friction because, your hair becomes positively charged, and the balloon becomes negatively charged. Touching a doorknob while getting electric charge and rubbing your shoes on the carpet causes friction.
What is gravity?
When the gravitational force pulls a chair and a bed, how do they attract together?
A force of attraction between objects that is due to their masses.
the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater force.
A rocket taking off is an example of which of Newton's laws?
What is the 3rd law of mtion.
why does speed and motion matter?
Why was time created?
ACCORDING TO archaeological evidence, the Babylonians and Egyptians began to measure time at least 5,000 years ago, introducing calendars to organize and coordinate communal activities and public events, to schedule the shipment of goods and, in particular, to regulate cycles of planting and harvesting.
