Acceleration, F=MA & Speed Flashcard (Honors) - End of 1.2 Exam

Front

What is the definition of velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken: Speed = Distance / Time.

Front

What is the formula for acceleration?

Back

Acceleration is calculated using the formula: Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.

Front

What is the definition of force?

Back

Force is how hard we push on something.

Front

What is the unit of force in the SI system?

Back

The unit of force in the SI system is the Newton (N).

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

According to Newton's second law, Force (F) = Mass (m) x Acceleration (a) or F = ma.

Front

If a car accelerates from 0 to 60 m/s in 5 seconds, what is its acceleration?

Back

Acceleration = (60 m/s - 0 m/s) / 5 s = 12 m/s².

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What does it mean if an object is in motion?

Back

An object is in motion if its position changes relative to a reference point over time.
