Force and Motion https://www.youtube.com/watch?v=8iKhLGK7HGk https://www.youtube.com/watch?v=8iKhLGK7HGk
Motion Motion is an object changing its position over time. How far an object moved in a certain amount of time. Often shown in Miles Per Hour (MPH) or meters per second (mps).
Force A push or a pull Force can be applied to an object to change it’s motion. Force can make an object in motion change it’s direction
Balanced Force Balanced forces cause an object to stay in place. A table can represent a balanced force: Gravity is pulling it down while the floor is pushing up on it with equal force. The table remains still.
Unbalanced Force Unbalanced forces cause objects to start moving, stop moving, or change direction. Unbalanced forces change the motion of objects. 3 factors: direction of force applied, strength of the force, mass of the object.
Direction The direction that a force is applied will determine the direction of the motion of the object.
Gravitational Force “Gravity” The attraction one object has for other objects. All objects exert a gravitational force on all other objects. The more matter an object has, the more gravity it will have.
Friction A force that acts in the opposite direction of an objects motion. When objects touch their surfaces interact. Moving one surface across another creates friction. If you rub the surface of your hands together quickly you will feel heat, heat is created by friction. https://www.youtube.com/watch?v=MAqrWvkBoHk
Air Resistance Friction between a moving object and the air it is passing through. If you hold your hand out of a car window while traveling you will feel air resistance. Air resistance keeps race cars from going any faster.
