Unbalanced force:
A force that causes a change in the motion of an object Inertia: A tendency of an object to do nothing or remain unchanged Linear force: A force that act in the same direction along a straight line Acceleration: The rate of change in velocity Velocity: The speed of an object in a given direction Reaction: An equal and opposite force exerted by an object against the other object that is exerting a force on Exert: To put to use a force on an object Act upon: To apply on an object or the presence of force in an object Force: A push or pull upon an object resulting from the object’s interaction with another object Momentum: The quantity of motion that an object has At rest: An object being stationery without any external force acted upon it Net force: The sum of all forces acting on an object Equal: Being evenly proportioned or balanced Constant: Not changing or varying continuously Motion: A change in position of an object with a respected time External force: A force caused by external agent outside the system Balanced force: Two individual force that are equal in magnitude but opposite in direction Weight: The amount or quantity of heaviness or mass Tension: The force that is transmitted through a string, rope, cable or wire when it is puled tight by forces acting from opposite ends Action-reaction: A pair of force that acted upon two interacting object Magnitude: How big something is or quantity Simultaneous: Something that is occurring, operating or done at the same time Friction: A surface resistance to relative motion Opposite direction: An object or something going on an opposing direction 1.) What did you like about Physics class in Term 1? The physics class is actually not as boring as I first thought it would be. Mr Jeff teach us in a way that all of us easily understands him and we didn’t get bored with the subject easily, despite how hard the subject is ( ;_; ). I like how there is coffee in the class (even though I never tried it cause its always out of glass) that makes us not sleepy since our class is always after recess. I also like how there isn’t any homework and the only homework we got is only unfinished workshops. 2.) Is there anything you would like to change in physics class? What I would like to change is probably the workshop type, like maybe we can learn by playing games, watching video or doing projects but not just workshop all the time because its kinda boring. 3.) Explain what you learned about vectors and scalars in Term 1! I learned that vectors and scalars are both physical quantities, the only difference is that vectors has direction while scalar doesn’t. Example of vector is pressure, velocity and acceleration. Example of scalars are length, weight and temperature. Resultant vectors are the result of adding two or more vectors and it is where the object end up moving despite having lots of vector on it. 4.) Explain what you have learned about velocity and acceleration so far! Velocity and acceleration are both vectors. Velocity is the rate of changer or displacement, the difference with the speed is that velocity is displacement per time while speed is distance per time. Acceleration is the change of velocity with certain time. |
