• Force -✓✓Any push or pull, contact forces like friction, air resistance,
tension, or non-contact forces like magnetism, electrostatic forces, and
gravity
• Vector Representation -✓✓Forces shown with arrows indicating
direction and magnitude, where length represents force size
• Resultant Force -✓✓Force when two forces act on an object, found
by vector addition, considering direction
• Balanced Forces -✓✓Forces summing to zero, object maintains
constant velocity, follows Newton's first law of motion
• Scalar vs. Vector -✓✓Magnitude-only vs. direction-inclusive
measurements, e.g., displacement vs. distance
• Weight -✓✓Force due to gravity acting on an object, calculated as
mass * gravitational field strength
• Work Done -✓✓Energy transferred by a force, calculated as force *
distance moved
, • Hooke's Law -✓✓Force equals spring constant times extension, for
elastic objects returning to original shape
• Gravitational Potential Energy -✓✓Energy stored in an object due to
its height above the ground, calculated as mass * gravity * height
• Moment -✓✓Turning force around a pivot, calculated as force *
distance to pivot, measured in newton meters
• Pressure -✓✓Force per unit area, calculated as force divided by area,
measured in pascals (Pa)
• Gas Pressure -✓✓Result of gas particles colliding with surfaces,
affected by volume, temperature, and gas quantity
• Acceleration -✓✓Rate of change of speed or velocity, calculated as
change in speed over time, measured in m/s^2
• Velocity-Time Graph -✓✓Graph showing velocity changes over time,
gradient represents acceleration
