Front

What is an example of Newton's first law of motion?

Back

An air freshener hanging from the rear-view mirror of a car hangs still while the car moves forward with a constant acceleration.

Front

What amount of force is needed to keep a cannonball moving in frictionless space after it is fired?

Back

Zero, since no force is required to keep it moving.

Front

What is Newton's first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the definition of net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What is inertia?

Back

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

Front

What does it mean for forces to be balanced?

Back

Forces are balanced when they are equal in size and opposite in direction, resulting in no change in motion.

Front

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

Back

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