Q: Displacement
Answer:
- it refers to the distance that a object is from its starting point
Q: Motion
Answer:
- when an object is motion its displacement is constantly changing
Q: - it is describe by displacement, velocity, and acceleration
Speed
Answer:
- refers to the distance traveled by an object per unit of time.
Q: velocity - - refers to speed in a given direction; therefore it tells us two things about a moving object
Answer:
its speed and its direction
Q: acceleration
Answer:
- refers to to any change of velocity either positive or negative.
Q: deceleration
Answer:
- refers to the negative acceleration or a decrease in velocity and can cause a change in direction
Q: momentum
Answer:
- is equal to the mass of an object multiplied by its velocity
Q: - Momentum = (Mass)(Velocity)
conservation of momentum
Answer:
- States that the total momentum of an isolated system is always constant
Q: -Ex
Answer:
,during a collision between two bodies, the momentum of each body changes, but the total momentum is is conserved. One
object may lose momentum, but the momentum lost by the object is gained by the other.
Q: vector
Answer:
- velocity and acceleration can both be described using vectors because they both have magnitude and direction.
Q: Newton's First Law
Answer:
- states that objects in motion tend to stay in motion and that objects at rest tend to stay at rest
Q: inertia
Answer:
- is the property of matter that resist any change in motion
Q: Newton's second law
Answer:
- describes the relationship between force, mass,and acceleration.
Q: - it states that force is applied on an object equals the mass of the object times its acceleration
force
Answer:
F= ma
Q: newton
Answer:
- (N) is the unit that represents a force that accelerates a mass of 1 kilogram 1 meter per second
Q: friction
Answer:
- sliding box along a floor, giving it velocity, it does not continue at that speed but stops. This is due to friction between
the box and floor
Q: - whenever a force is exerted along a surface or whenever an object has a velocity along the surface, and the two
surfaces touch, there is force called friction
gravity
Answer:
- is the force of attraction between all objects in the universe
Q: weight
Answer:
, - the pull of gravity on an object determines its weight
Q: torque
Answer:
- the ability of a force that is applied perpendicularly to rotate an object around an axis, such as using a wrench to turn a
bolt is measured by the quantity torque
Q: - is the perpendicular force times the lever arm
lever arm
Answer:
- is the distance from the axis of rotation to the point where force is exerted. The farther it is form the axis of rotation , the
easier it is to rotate the object and the more torque is produced
Q: centripetal force
Answer:
- to keep a ball at the end of a string moving in a circle, you must continually exert a force pulling the ball back towards
the center
Q: Newton's third law
Answer:
- states that for every action there is an equal and opposite reaction
Q: -Ex
Answer:
the blast from the back of the rocket pushes the rocket froward
Q: energy
Answer:
- is the ability to do work
Q: kenetic energy
Answer:
- is energy associated with motion. Any moving body has this type of energy because it it is able to do work by moving
other bodies
Q: K.E = 1/2(mass * velocity)^2
potential energy
Answer:
- is energy stored in a body because of its position. When you lift a body you provide it with potential energy. An object
has more potential energy when it is on top of a building than on the first floor
