• Course instructor: Dr. Anas Agamia
• Staff assistance: Saeed Ali, Aml alsoudi, Esraa Draz
• Course includes lectures and practical sessions
• Topics covered include statics, force, torque, equilibrium, measurement of short length using calipers, center of mass, stability, simple pendulum, levers, temperature, heat, metabolic rate, therapeutic heat and cold, temperature measurements, electrostatic forces, Ohm's law, electric fields, capacitors, dielectrics, RC circuits, bioelectricity, time constant of RC circuit, measurements of length of a molecule , effect of temperature on cell membranes, electrical signals (EMG, ECG, EEG, ERG, EOG).
• Topics also include resolving forces, torque, reaction forces, torque and reaction forces in different situations (arm curl, lifting a box, standing on toes), moments of forces, magnitude and distance to pivot point, angle, moment of a force=Fd sinθ, moment arm, torque is related to rotational motion not force, torque created when line of action of force does not pass through center of rotation.
• Equilibrium includes static and dynamic equilibrium, conditions for rigid body in static equilibrium (net force = zero, net torque = zero), examples of equilibrium types (stable, unstable, neutral equilibrium).

Biophysics Definition

• Biophysics is a branch of science concerned with the application of physical methods and principles to biological problems.
• It links physics and biology.

Force Definition

• Force is a physical quantity that tends to accelerate or decelerate an object, or change its shape.
• Force is a push or a pull.
• A single force can be resolved into horizontal and vertical components.

Vectors

• Vectors are represented with arrows
• Magnitude of force is equal to the length of the arrow
• Direction of force is the head of the arrow.

Torque (Moment of force)

• Torque is a moment of force which is a rotational force.
• It is a measure of the turning effect of a force about a point.
• Torque = Force x perpendicular distance from the axis of rotation.
• Torque is determined by the magnitude of applied force, distance from the pivot point, and the angle (direction) of the applied force.
• Positive torque is counter-clockwise, negative torque is clockwise.
