Warm-up- Newton's 2nd Law

Front

What is the unit for acceleration?

Back

m/s²

Front

Which wagon will require more force to move?

Back

Bottom wagon, because it has more mass.

Front

Acceleration is a change in...

Back

Velocity

Front

As force applied to a textbook increases, what happens to its acceleration?

Back

Increases

Front

The larger the mass you have the _____ force you need to change its motion.

Back

more

Front

What does Newton's 2nd Law state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the formula for Newton's 2nd Law?

Back

F = m * a (Force = mass × acceleration)

Front

If a 10 kg object is accelerated at 2 m/s², what is the force applied?

Back

20 N (F = m * a = 10 kg * 2 m/s²)

Front

What happens to acceleration if mass increases while force remains constant?

Back

Acceleration decreases.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.
