Back

Inertia

Front

Inertia is _________________________

Back

the tendency to resist any change in motion.

Front

The more mass an object has the more inertia it has. True or False?

Back

True

Front

What happens to an object at rest when no unbalanced forces act on it?

Back

It remains at rest.

Front

What happens to an object in motion when no unbalanced forces act on it?

Back

It continues to move at a constant velocity.

Front

Define unbalanced forces.

Back

Forces that cause a change in the motion of an object.

Front

What is the effect of balanced forces on an object?

Back

The object remains in its current state of motion.

Front

If a box is pushed with 300 N to the left and 200 N to the right, which way does it move?

Back

Left 100 N.

Front

What is inertia dependent on?

Back

The mass of the object.

Front

Give an example of inertia in everyday life.
