What is force?

A push or pull on an object.

100

What is motion?

an object will not change its motion unless a force acts on it.

100

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.

100

What is Friction?

force that resists the sliding or rolling of one solid object over another.

100

What is Direction?

Direction is the location of something relative to something else.

True or false: Is pushing a ball, a force?

True

200

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

  • It produces heat, that helps in heating parts of any object or to warm ourselves.
  • It also causes loss in power.
  • It produces noise during any kind of operation.
  • It's because of friction that we're able to walk, run, play, etc

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

300

What is the formula for force

F=M*A or Force equal mass times acceleration.

300

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.

300

what are the four types of speed?

There are four types of speed which are uniform speed, variable speed, average speed, and instantaneous speed.

300

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.

300

what are the main points in direction?

north, east, south, west

400

What is newton's second law?

force


400

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.

400

what does speed tell you?

Speed tells you how fast

400

what are five examples of friction?

  • Walking on the road.
  • Writing on notebook/ blackboard.
  • Flying of aeroplanes.
  • Drilling a nail into wall.
  • Sliding on a garden slide.
400

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.

500

What causes force to change?

Unbalanced forces

500

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.

500

what are five examples of speed

Moving on tracks, Flying in sky, Satilite orbiting earth, Earth revolving around sun.

500

what is needed for frition?

 1) the roughness of the surfaces (or the "coefficient of friction") and 2) the force between the two objects

500

what are the three main directions called?

Cardinal directions
