Physics Flashcard on Motion

Front

What is relative motion?

Back

Relative motion is the calculation of the motion of an object with regard to some other moving object. For example, two people standing on a moving walkway appear to be moving relative to a stationary observer.

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which the components are connected end-to-end, so that the current flows through each component in turn. If one component fails, the entire circuit is broken.

Front

What is a parallel circuit?

Back

A parallel circuit is an electrical circuit where multiple components are connected across the same voltage source. If one component fails, the others can still function.

Front

What does Ohm's Law state?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). It is expressed as V = IR.

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave in which the particles of the medium move parallel to the direction of the wave's propagation. Sound waves are a common example.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the particles of the medium move perpendicular to the direction of the wave's propagation. Light waves are an example of transverse waves.

What happens to light when it passes from air into water?

Back

When light passes from air into water, it slows down and bends towards the normal line, which is an imaginary line perpendicular to the surface at the point of incidence.

Front

What is the normal line in optics?

Back

The normal line is an imaginary line that is perpendicular to the surface at the point where a wave (like light) strikes the surface.

Front

What is the formula for calculating speed?

Back

Speed is calculated using the formula: Speed = Distance / Time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It can be calculated using the formula: Acceleration = (Final Velocity - Initial Velocity) / Time.
