Motion, Speed, and Energy Reteach Practice

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is the energy stored in an object due to its position or state, while kinetic energy is the energy of an object in motion.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating potential energy?

Back

Potential energy (PE) = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, typically expressed in meters per second (m/s).

Front

What is the definition of velocity?

Back

Velocity is the speed of an object in a specific direction, expressed in meters per second (m/s) with a directional component.

Front

What is the formula for calculating average speed?

Back

Average speed = Total Distance / Total Time.

Front

What are examples of chemical potential energy?

Back

Wood, batteries, gasoline, and food are all examples of chemical potential energy.

Front

How does energy conservation apply to roller coasters?

Back

In a roller coaster, the total mechanical energy (potential + kinetic) remains constant if we ignore friction and air resistance.

Front

What is the relationship between speed and distance in a time graph?

Back

The slope of a distance-time graph represents speed; a steeper slope indicates a higher speed.

Front

What is the significance of the area under a velocity-time graph?

Back

The area under a velocity-time graph represents the total distance traveled.
