A description of how far it is from one point to another.
If gravity acts to pull an object down a hill, this acts to push it up.
The resistance to the change in motion by an object.
A measure of the pulling force of gravity.
The SI unit for distance.
F = m x a This is:
Newton’s Second Law of Motion
Also known as The Law of Inertia
Newton’s First Law of Motion
A Newton (N)
The rate of change in velocity
Acceleration due to gravity on the surface of the Earth
9.8 m/s/s or m/s 2
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 x a F = (1 kg)(9.8 m/s/s) F = 9.8 N
Acceleration, deceleration and a change in direction all can be caused when the net force is greater than ___
zero newtons (0 N)
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
A tow truck pulls a 2000 kg with a net force 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
Jumping on a trampoline is an example.
Newton’s Third Law of Motion
A pencil sitting on a desk (not moving) is an example.
Newton’s 1st Law
The SI unit of Force
Determines how much inertia an object has
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 Motion
What is the SI unit of Mass?
If you go to the moon, what happens to your mass
It does not change.
The amount of matter in an object
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.
Two factors in determining the amount of gravity between 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.
Weight decreases, mass remains the same.

Friction and Gravity. Warm up10/28 Define these words Friction Gravity Mass weight.
Describing Motion Newton’s Laws. First we need to define the word FORCE: The cause of motion (may cause objects to start/stop moving or change directions)
Motion & Forces Force A push or a pull *Cause an object to start moving, stop moving, or change direction.
Forces Pages 188 to 191. Forces Force - a push or a pull, measured in Newtons (N) Contact Force – is a push or a pull one object applies to another object.
Forces & Motion. Motion A change in the position of an object Caused by force (a push or pull)
Motion & Forces Vocabulary Match the words to the correct definition.
