MOTION chapter 13

Front

What is Newton's SECOND law of motion?

Back

Force = Mass x Acceleration

Front

How do you calculate acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time

Front

What is negative acceleration?

Back

Negative acceleration, or deceleration, describes an object slowing down.

Front

What does inertia mean?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the formula for average speed?

Back

Average Speed = Total Distance / Total Time

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What happens to an object in motion if no external force acts on it?

Back

It will continue to move at a constant velocity due to inertia.

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 is the effect of mass on acceleration according to Newton's second law?

Back

Greater mass results in less acceleration for the same amount of force applied.

Front

What is the relationship between force, mass, and acceleration?

Back

Force is directly proportional to mass and acceleration (F = m * a).
