Newton's 1st Law of Motion (Law of Inertia)
An object in motion stays in motion, and an object at rest stays at rest, unless acted upon by an unbalanced force.
Newton's 2nd Law of Motion (Force and Acceleration)
The greater the mass, the greater the force needed to accelerate the object. (Force = Mass x Acceleration)
Newton's 3rd Law of Motion (Action/Reaction)
For every action, there is an equal and opposite reaction.
The tendency of an object to resist a change in motion. The greater the mass, the more inertia.
The force exerted on objects that tend to pull the objects down toward the center of the Earth.
The force placed on a moving object opposite its direction of motion, and this causes a resistance to movement. Usually produces heat.
Any action that can change or cause motion. A force is any push or pull. Usually measured in Newtons (N). Forces can be represented with arrows called Vectors. Vectors show the direction and magnitude of a force.
Formula: Force = Mass x Acceleration (f=ma).
The sum of all the forces, with a direction. An object will move in the direction of the net (unbalanced) force.
The rate of change of velocity of with time. In other words, A change in speed and/or direction of an object's motion. Can be positive (speeding up), or negative (slowing down).
The amount of matter that an object has, usually measured in grams (g) or kilograms (kg).
The action or process of moving or being moved (movement of an object or body); a change in position.
The distance traveled by an object in a given amount of time. Speed is distance traveled in a certain time.
Formula: Speed = Distance/Time (s=d/t).
The total path length traveled from one point or location to another.
The measurement of the rate and direction of change in the position of an object. Velocity is a quantity that measures speed and gives direction.
Formula: Speed + Direction.
A unit of force, usually expressed in Joules.
When the net force on an object does not equal zero. Unbalanced forces change the speed or direction of an object's motion.
Something done as a result of effort or exertion.
Formula: Work = Force x Distance (w=fd)
The effect of gravity on an object's mass.
Formula: Weight = Mass x Gravity.
The product of the mass of an object and its velocity.
The distance between two locations measured along the shortest path connecting them, in a specified location (the shortest distance between two points).
