- any time there is a change in the movement of an object, what is true of the force pairs acting on the object.
- 3rd of Newton's laws of motion
- when a bird flies upward
- scale
- a device used to measure weight
- gravity
- a force that pulls a skateboarder down a slope
- speed
- is a measure of how far you move in a given time
- Newton
- a unit of measure used to measure weight
- 2nd of Newton's Laws of Motion
- when a golfer needs to hit a long distance, he uses a driver rather than an iron
- forces are balanced
- any time there is no change in the movement of an object, what is true of the force pairs acting on the object.
- gravity
- the measure of how much earth's gravity pulls down on an object
- km
- the symbol for kilometer
- isaac newton
- a scientist whose three important laws about how things move are named after
- Gravity
- a pull that every object exerts on every other object.
- friction
- push or pull that opposes motion between two surfaces that are touching each other.
- friction
- the force that opposes motion
- a=F//m
- acceleration=F/m
- mass
- is measured with a balance
- reaction
- a force that is opposite to an action
- acceleration
- a change in speed or direction, something is speeding up or slowing down
- force
- a push or pull
- average speed
- refers to the distance and time of an entire trip
- balanced forces
- when there in no movement
- inertia
- resistance to a change in movement
- m/s
- meters per second
- reaction force
- according to newton's third law, what is there for every action force.
- km/h
- kilometers per hour
- unbalanced forces
- when you step into quicksand
- a=f/m
- mathematical formula that describes Newton's second law.
- average speed
- describes the movement for an entire trip
- inertia
- name for resistance to a change in motion. An object at rest tends to stay at rest, and a moving object tends to keep movin in a straight line until it is affected by a force.
- scientific law
- a theory that has been tested many times and the results are the same each time. Its an accurate description of some important part of the natural world.
- Weight
- a measure of how much Earth's gravity pulls down on an object
- (m/s)/s
