SC.5.P.13.4 Investigate and explain that when a force is applied to an object but it does not move, it is because another opposing force is being applied by something in the environment so that the forces are balanced.
SC.5.P.13.1 Identify familiar forces that cause objects to move, such as pushes or pulls, including gravity acting on falling objects.
SC.5.P.13.2 Investigate and describe that the greater the force applied to it, the greater the change in motion of a given object.
SC.5.P.13.3 Investigate and describe that the more mass an object has, the less effect a given force will have on the object’s motion.
SC.4.L.16.1 Identify processes of sexual reproduction in flowering plants, including pollination, fertilization (seed production), seed dispersal, and germination.ForcesBy: chloee weilandvocab:force- a push or pull, which may cause a change in an object's motion. Gravity- the force of attraction between two objects, such as the attraction between Earth and objects on it.Friction- a force that acts between two touching objects and that opposes motion. Balanced forces- forces that cancel each other out because they are equal in size and opposite in direction. Unbalanced forces- forces that cause a change in motion because they act on an object and dont cancel each other out.

velocity-the speed and direction of an object's motion.
Work- energy used when a force moves an object.
Power-the rate at which work is done.
Equilibrium-the state in which net force is zero.
Inertia-the tendency of an object to resist a change in motion.
Acceleration- the rate at which the velocity of an object changes over time.
Machine- a device that changes the direction or the amount of effort needed to do work.

  • A push or pull can be pulled measured with a spring scale in units called newtons.Smaller forces cause smaller change.
  • A push or pull can act on an object. Forces can make objects move speed up, slow down or change direction.
  • Gravity is a force of attraction between two objects. The size of this object can increase as the mass of the object increases.
  • Gravity, electricity, magnetism snd electric forces can act between objects even if they are not touching.
  • A monorail is a good example of a magnetic force. The magnetic force causes this monorail to float above the track. The magnetic force are also used to make the monorail move along the track at very high speed.
  • Work is done when a force moves an object. To calculate work, you multiply the force ( in newtons) acting on an object by the distance the force causes the object to move.
  • The formula to calculate work is force x distance = work
  • Work is measured in joules. One joule (j) is the amount of work done when a force of 1 newton moves an object a distance of 1 meter.
  • Power is the rate at which work is done. When work is done faster, power is increased.
  • For example walking up a hill and running up the same hill take the same amount of work. Since running up the hill is fater than walkingg, the amount of power needed to run is greater.
  • You can calcuate the amount of power for a certain amunt of work. Divide the amount of work done by the amount of time to do the work. Watts are the unitsof power.
  • work/time = power is the calcution for power.
  • The table below shows that the amount of power will double if a person doubles the amount of work done during a certain amount of time.
  • Review Newton's law of motion
20J/4s = 5w
40J /4s = 10w
2 s
20J/2s = 10W

10N x 1M = 10J
10N X 2M = 20J
20n x 2M = 40J
