Exploring Motion and Time

What is a simple pendulum?

• A simple pendulum is a device that generates electricity using magnets.

• A simple pendulum is a type of clock that uses gears to measure time.

• A simple pendulum is a mass attached to a fixed point by a string or rod that swings back and forth.

• A simple pendulum is a mass that floats on water and moves in circular motion.

How does a simple pendulum demonstrate periodic motion?

• It exhibits periodic motion by vibrating rapidly.

• It demonstrates periodic motion by spinning in circles.

• A simple pendulum demonstrates periodic motion by swinging back and forth in a regular, repeating pattern.

• It shows periodic motion by moving in a straight line.

What is the formula for the period of a simple pendulum?

• T = √(L/g)

• T = 2π√(g/L)

• T = 2π√(L/g)

• T = 2π(L/g)

What units are commonly used to measure time?

• grams

• liters

• kilometers

• seconds, minutes, hours, days, weeks, months, years

How do you convert seconds into minutes?

• Multiply the number of seconds by 60.

• Add 60 to the number of seconds.

• Divide the number of seconds by 60.

• Subtract 60 from the number of seconds.

What is uniform motion?

• Motion in a circular path at varying speeds.

• Motion that varies in speed and direction.

• Uniform motion is motion at a constant speed in a straight line.

• Motion that involves acceleration and deceleration.

Give an example of uniform motion in everyday life.

• A bicycle accelerating down a hill.

• A train coming to a stop at a station.

• A person jogging with varying speeds.

• A car traveling at a constant speed of 60 km/h on a highway.

What is non-uniform motion?

• Uniform motion with constant speed

• Motion that occurs in a straight line only

• Non-uniform motion is motion with varying speed or direction.

• Motion that is always accelerating

How does non-uniform motion differ from uniform motion?

• Uniform motion can change direction while maintaining speed.

• Non-uniform motion occurs only in circular paths.

• Non-uniform motion is always faster than uniform motion.

• Non-uniform motion differs from uniform motion in that it involves changes in speed or direction, while uniform motion maintains a constant speed in a straight line.

What is speed?

• Speed is the amount of force applied to an object.

• Speed is the temperature of an object.

• Speed is the rate at which an object covers distance.

• Speed is the color of an object.
