• Contact Force


  A force transmitted through physical contact between objects, such as friction and normal force.
• Force


  A push or pull that can cause an object to change its motion or shape.
• Motion


  The change in position of an object over time.
• Friction

  A force that opposes motion between two surfaces in contact.
• Net Force

  The sum of all the forces acting on an object.
• Free Body Diagrams


  Drawings that show the forces acting on an object.
• Static Friction

  The force that opposes the initially stationary object from moving.
• Rolling Friction


  The force that opposes the motion of an object rolling along a surface.
• Velocity-Time Graphs


  A graph showing the relationship between an object's velocity and time.
• Circular Motion


  Motion along a circular path.
• Kinetic Energy


  The energy an object possesses due to its motion.
• Work


  The amount of energy transferred between an object and its environment through force.
• Elastic Collisions


  Collisions where kinetic energy is conserved.
• Gravitational Potential Energy


  The energy an object possesses due to its height or position.
• Momentum


  The product of an object's mass and velocity.
• Acceleration

  A change in velocity, resulting from the application of a force.
• Deceleration


  A change in velocity in the opposite direction of the applied force.
• Change in Direction


  A change in the direction of an object's motion, resulting from a force.
• Elastic Collision


  A collision where the total kinetic energy is conserved.
• Inelastic Collision


  A collision where the total kinetic energy is not conserved.
