Graphing Energy and Motion Review

Front

What does a graph representing constant speed look like?

Back

A straight line on a distance-time graph indicates constant speed.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

How does direction change relate to acceleration?

Back

A change in direction is considered acceleration, even if the speed remains constant.

Front

What happens to kinetic energy when speed doubles?

Back

Kinetic energy quadruples when the speed of an object doubles.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What does a steep slope on a distance-time graph indicate?

Back

A steep slope indicates a high speed.

Front

What does a flat line on a distance-time graph represent?

Back

A flat line indicates that the object is stationary.

Front

What is the formula for calculating kinetic energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What happens to an object's kinetic energy if its mass is doubled while speed remains constant?

Back

The kinetic energy doubles if the mass is doubled while speed remains constant.

Front

What is the relationship between speed and kinetic energy?

Back

Kinetic energy is proportional to the square of the speed; as speed increases, kinetic energy increases exponentially.
