Acceleration Flashcard

Front

What does negative acceleration indicate about an object's motion?

Back

The object is slowing down.

Front

In which scenario does a car have no acceleration?

Back

A car with the cruise control set at 80 km/h going down a straight highway.

Front

What occurs whenever an object accelerates?

Back

The object speeds up, slows down, or changes directions.

Front

Calculate the acceleration of a drag racer that goes from 0 m/s to 200 m/s in 5 seconds.

Back

40 m/s².

Front

What is the SI unit used to measure time?

Back

s (seconds).

Front

Define acceleration in physics.

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What does it mean if an object has a constant velocity?

Back

The object is not accelerating.

Front

What is the effect of acceleration on an object's speed?

Back

Acceleration can increase or decrease an object's speed.

Front

What is the relationship between acceleration and force according to Newton's second law?

Back

Force = Mass × Acceleration.
