SCIENCE WEEK 1

• The acceleration of an object as produced by a net force directly proportional to the magnitude of the net force, in the same direction as the net force, inversely proportional to the mass of the object.
• Second law of motion- Acceleration
• the larger the force on an object, the larger it's acceleration
• Scalar- A quantity that is completely described by it's magnitude.
• Vector- A quantity that has both magnitude and direction.
• Acceleration is defined as the rate of change in velocity with time
• speedometer- measures speed of vehicle in km/h or mph
• Speed- The change of it's position over time or the magnitude of the change of it's position per unit of time
• Velocity- Has rate of speed and direction
• Odometer- it records the distance traveled
• Uniform acceleration- acceleration is the same in all directions, so the velocity is constant.
• Uniformly accelerated motion- the value of acceleration is constant. it does not change. the velocity changes but at it's constant rate.
