newtons laws
An object in motion will stay in motion.
what is the 1st law
My mass would change if I went to a different planet. True or False
false
If you say,"A bird is going 30mi/hr west." you are stating its _______.
What is Velocity
True or False. A bike on grass is a form of friction?
what is true
strength or energy as an attribute of physical action or movement.
what is force
A rocket taking off is an example of which of Newton's laws? A.1st B.2nd C.3rd
what is 3rd
Is it easier to stop a moving object that has MORE mass or LESS mass?
It's easier to stop a moving object with LESS mass.
True or False:Velocity is the time it takes for a change to happen?
Which is a form of decreasing friction intentionaly? A. Putting snow tires on a car when the road is icy. B.Oil on a a squeaky door hinge. C.Wearing cleats in field sports. D.None of the above.
what is b
the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.
what is net force
Which of Newton's laws states: That an object at rest will stay at rest and an object in motion will stay in motion at a constant velocity, unless acted upon by an unbalanced force. A.1st B.2nd C.3rd
what is 1st
If you are in a bus on a field trip, are the trees outside the bus really moving or are you?
what is You are moving
True or False: acceleration is speed times inertia.
what is false
What is the definition of friction? Be close to the answer for credit.
What is when two surfaces rub together and prevents or slows motion.
the quantity of motion of a moving body, measured as a product of its mass and velocity.
what is momentum
Which of Newton's Laws states: That for every action there is an equal and oppostite reaction. A.1st B.3rd C.2nd
what is 3rd
If I am slowing down in the car, is that acceleration?
what is YES
What is inertia. A.When you have a stomach cramp B.When an object resists a change in it's state in motion C.When an object accelerates D.A force that pulls two objects together
what is B
True or False. Using snow tires on an icy road is an example of increasing friction.
what true
a numerical measurement of how far apart objects are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria. In most cases, "distance from A to B" is interchangeable with "distance from B to A".
what is distance
true or false :Force equals mass times acceleration.
what is true
Everything in the universe is in _____________.
Motion
does Friction decreases speed
what is yes
Which one of these two are true? A.Friction takes place when you go down a slide. B.Friction takes place when you try to go down a street block on a metal sled.
what is b
the rate of change of velocity of an object with respect to time. An object's acceleration is the net result of all forces acting on the object, as described by Newton's Second Law.
acceleration
