A description of how far it is from one point to another

A description of how far it is from one point to another.


Distance

Distance


If gravity acts to pull an object down a hill this acts to push it up

If gravity acts to pull an object down a hill, this acts to push it up.


Friction

Friction


The resistance to the change in motion by an object

The resistance to the change in motion by an object.


Inertia

Inertia


A measure of the pulling force of gravity

A measure of the pulling force of gravity.


Weight

Weight


The si unit for distance

The SI unit for distance.


Meter

Meter


F m x a this is

F = m x aThis is:


Newton s second law of motion

Newton’s Second Law of Motion


Also known as the law of inertia

Also known as The Law of Inertia


Newton s first law of motion

Newton’s First Law of Motion


Kg m s s

kg.m/s/s


A newton n

A Newton (N)


The rate of change in velocity

The rate of change in velocity


Acceleration

acceleration


Acceleration due to gravity on the surface of the earth

Acceleration due to gravity on the surface of the Earth


9 8 m s s or m s 2

9.8 m/s/s or m/s2


What is the weight of an object with a mass of 1 kilogram

What is the weight of an object with a mass of 1 kilogram?


F m 1 kg a 9 8 m s s

F = ?m = 1 kga = 9.8 m/s/s

F = m x a

F = (1 kg)(9.8 m/s/s)

F = 9.8 N


10 pt

Acceleration, deceleration and a change in direction all can be caused when the net force is greater than ___


Zero newtons 0 n

zero newtons (0 N)


10 pt

As a box is sliding down a ramp, a 10 newton force of gravity is pulling the box down while a 2 newton force of friction acts to stop the box. What is the net force accelerating the box down the ramp?


10 n 2 n 8 n

10 N – 2 N = 8 N


A tow truck pulls a 2000 kg with a net force of 4000 n what is the acceleration of the car

A tow truck pulls a 2000 kg with a netforce of 4000 N.What is the acceleration of the car?


A f m m 2000 kg f 4000 n 4000 n 2000 kg a 2 m s s or m s 2

a = F ÷ m m = 2000 kg F = 4000 N4000 N ÷ 2000 kga =2 m/s/sor m/s2


Jumping on a trampoline is an example which law of motion

Jumping on a trampoline is an example which Law of Motion.


Newton s third law of motion

Newton’s Third Law of Motion


A pencil sitting on a desk not moving is an example

A pencil sitting on a desk (not moving) is an example.


Newton s 1st law

Newton’s 1st Law


The si unit of force

The SI unit of Force


The newton

The Newton


Determines how much inertia an object has

Determines how much inertia an object has


The mass of the object

The mass of the object.

A person flies through the windshield of the car because she did not have their seatbelt on. This is an example of


Newton s first law of motion1

Newton’s First Law of Motion


What is the si unit of mass

What is the SI unit of Mass?


Kilograms

kilograms

If you drop a penny, an elephant, and a puppy at the same time from the same height, which would hit the ground first (ignoring air resistance)?


They would all hit at the same time

They would all hit at the same time.


Two factors in determining the amount of gravity between two objects

Two factors in determining the amount of gravity between two objects.


The mass and the distance between the two objects

The mass and the distance between the two objects


This is what happens to your weight and mass when you go to the moon

This is what happens to your weight and mass when you go to the moon.


Weight decreases mass remains the same

Weight decreases, mass remains the same.
