CARD #1ACTIVE RECALL
Q: What is the formula for Centripetal Force?
A: F = (m * v^2) / r, where m is mass, v is velocity, and r is the radius of the circular path.
💡 Acts perpendicular to the velocity vector, pointing towards the center.

CARD #2ACTIVE RECALL
Q: State the Work-Energy Theorem.
A: The net work done by all forces acting on a particle equals the change in the kinetic energy of that particle: W = ΔKE.
💡 Applies to both conservative and non-conservative forces.
CARD #3ACTIVE RECALL
Q: What is the formula for Torque in rotational motion?
A: τ = r * F * sin(θ), where r is the distance from the pivot, F is force, and θ is the angle between them.
💡 Calculated as the cross product of position vector and force vector.
CARD #4ACTIVE RECALL
Q: Define the term 'Escape Velocity'.
A: The minimum speed required for a body to escape from the gravitational influence of a primary body: v = √(2GM/R).
💡 For Earth, it is approximately 11.2 km/s.
CARD #5ACTIVE RECALL
Q: What is the formula for the time period of a Simple Pendulum?
A: T = 2π * √(L / g), where L is the pendulum length and g is acceleration due to gravity.
💡 Independent of the mass of the bob.
CARD #6ACTIVE RECALL
Q: What is Hooke's Law?
A: F = -k * x, where F is restoring force, k is the spring constant, and x is displacement from equilibrium.
💡 The negative sign indicates the force is restoring.
