Force
What is force?
A push or pull on an object.
What is motion?
an object will not change its motion unless a force acts on it.
What is Speed?
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.
What is Friction?
force that resists the sliding or rolling of one solid object over another.
What is Direction?
Direction is the location of something relative to something else.
True or false: Is pushing a ball, a force?
True
True or false: When a pencil is still and it does not move it have motion?
False
True or False: if a car travels 70 miles in one hour, the car is traveling at a speed of 70 miles/hour (miles per hour). is it speed.
true
what is an affect on friction
what is a specific meaning to direction?
Cardinal directions or cardinal points are the four main directions or points of the compass: north, east, south and west. These direction are also written in short form as N, E, S and W. North and south are directed towards the north and south poles of the Earth. The Earth's rotation defines east and west
What is the formula for force
F=M*A or Force equal mass times acceleration.
What is Newton's first law?
every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
what are the four types of speed?
There are four types of speed which are uniform speed, variable speed, average speed, and instantaneous speed.
what are the three things friction depends on?
(1) the material of the bodies in contact. (2) quality of machining of the surface in contact. (3) presence of foreign matter between the surface.
what are the main points in direction?
north, east, south, west
What is newton's second law?
force
what are the three main topics of motion?
Topics covered in the lesson are Rest and Motion, Acceleration, Types of Motion, Distance Time Graphs, Scalar and Vector Quantities, Velocity Time Graphs, Distance and Displacement, Derive Three Equations of Motion, Uniform & Non Uniform Motion, Circular Motion, Speed, Velocity.
what does speed tell you?
Speed tells you how fast
what are five examples of friction?
what ra ethe five types of direction?
There are five different types of following directions. These include basic directions, sequential directions, quantitative and spatial directions, temporal directions, and conditional directions.
What causes force to change?
Unbalanced forces
what do you have to know about motion?
Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed and frame of reference to an observer and measuring the change in position of the body relative to that frame with change in time.
what are five examples of speed
Moving on tracks, Flying in sky, Satilite orbiting earth, Earth revolving around sun.
what is needed for frition?
1) the roughness of the surfaces (or the "coefficient of friction") and 2) the force between the two objects
what are the three main directions called?
Cardinal directions
