Newtons first law review 7.7D

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

How does mass relate to inertia?

Back

Objects with greater mass have greater inertia, meaning they are harder to start or stop moving.

Front

What happens to a moving object if no unbalanced force acts on it?

Back

A moving object will continue to move at a constant velocity in a straight line.

Front

What is a net force?

Back

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

Front

What is the result of balanced forces on an object?

Back

Balanced forces do not change an object's motion; the object remains at rest or continues to move at a constant speed.

Front

What type of forces cause a change in motion?

Back

Unbalanced forces cause a change in an object's motion.

Front

What does Newton's first law state?

Back

Newton's first law states that an object will remain at rest or in uniform motion unless acted upon by an unbalanced force.

Front

Can Newton's first law apply to nonmoving objects?

Back

Yes, Newton's first law applies to both moving and nonmoving objects.

Front

If a car is moving at a constant speed and suddenly hits a wall, what happens?

Back

The car will stop suddenly due to the unbalanced force of the wall acting on it.

Front

What is an example of inertia in everyday life?

Back

When a bus suddenly stops, passengers lurch forward due to inertia.
