Science 9

• •It is defined by a motion in a straight line with a constant acceleration and zero difference. •When an object is travelling in a straight line with an increase in velocity at equal intervals of time, then the object is said to be in uniform acceleration. •Is the motion of an object where the acceleration is constant.

  UNIFORMLY ACCELERATED MITION
• •The actual length is covered by an object. •It is a scalar quantity meaning it only has a numerical value.

  DISTANCE
• •The straight line or short cut from the initial position to the final position with direction. •It is a vector quantity which means it both has a numerical value and direction.


  DISPLACEMENT
• •Is how fast you are traveling.-e.g. riding a car with a speed of 20 m/s.

  SPEED
• •The speed in a given direction.-e.g. riding a horse with a speed of 20 m/s going to wall.

  VELOCITY
• •Is defined as a projectile motion in a horizontal plane depending upon the force acting on it.

  HORIZONTAL DIMENSION
• •The change in velocity over time. •Means, that there is a change or variation of distance at a given time-eg. the car's accelerating at 20m/s², 7 20m/s².

  ACCELERATION
• •Is any motion of a body where its weight is the only force acting upon it. •When a falling object is free from all forces. •No friction or air resistance.
