SP3. Students will evaluate the forms and transformations of energy.
a. Analyze, evaluate, and apply the principle of conservation of energy and measure the
components of work-energy theorem by
• describing total energy in a closed system.
• identifying different types of potential energy.
• calculating kinetic energy given mass and velocity.
• relating transformations between potential and kinetic energy.
b. Measure and calculate the vector nature of momentum.
c. Compare and contrast elastic and inelastic collisions.
d. Demonstrate the factors required to produce a change in momentum.
e. Analyze the relationship between temperature, internal energy, and work done in a physical system.
f. Analyze and measure power.
Magnetic forces are very powerful, and are used to attract materials towards the magnet. In the picture, because the nails are made of a magnetic material that are attracted to the magnet, the nails are pulled off the counter and towards the magnet.
SP5. Students will evaluate relationships between electrical and magnetic forces.
a. Describe the transformation of mechanical energy into electrical energy and the transmission of electrical
energy.
d. Determine the relationship between moving electric charges and magnetic fields
We see acceleration everyday, from cars flying past us, to us running down a hill. Acceleration occurs when there's a change in velocity, which happens when you speed up, slow down, or change directions. This picture is an example of how we measure acceleration in everyday life, most commonly in our cars by our speedometer.
SP4. Students will analyze the properties and applications of waves.
b. Experimentally determine the behavior of waves in various media in terms of reflection, refraction, and
diffraction of waves.
c. Explain the relationship between the phenomena of interference and the principle of superposition.
d. Demonstrate the transfer of energy through different mediums by mechanical waves.
In a collision, while it may look like on object receives the majority of the impact, both objects receive the same impulse during a collision. As for pool table balls, this is an elastic collision. What that means is when the cue ball breaks the pack of balls, all of the momentum from the cue ball is transferred to the other balls and they bounce off each other sending the cue ball in the opposite direction of the rest of the balls, and sending the pack of balls flying out in various directions.

In Newton's third law, it is proven that for every action there is an equal and opposite reaction. So, when the golf club strikes the golf ball, the ball applies the same amount of force to the golf club, but the golf ball goes much further than the golf club because their masses are very different.
SP1. Students will analyze the relationships between force, mass, gravity, and the motion of objects.
d. Measure and calculate the magnitude of frictional forces and Newton’s three Laws of Motion.
e. Measure and calculate the magnitude of gravitational forces.
f. Measure and calculate two-dimensional motion (projectile and circular) by using component vectors.
g. Measure and calculate centripetal force.
h. Determine the conditions required to maintain a body in a state of static equilibrium.
Friction is a major force that is used to slow down an object by applying a force in the opposite direction. A bike wheel brake is an example of this because when the brake presses down on the wheel friction begins to take place between the wheel and the pad slowing the wheel and bike down.
