8th Grade Physics/Energy Review (Day 1)

Front

What happens if you increase the Net Force of an accelerating object?

Back

The object increases speed.

Front

What unit do we measure force in?

Back

Newtons.

Front

What can balanced forces NOT result in?

Back

Changes in direction.

Front

Which of the following is NOT an example of unbalanced forces?

Back

A car traveling 60 mph constantly.

Front

What can be said about the inertia of a car that does not move when pushed?

Back

The inertia of the car is too great.

Front

Define Net Force.

Back

The total force acting on an object, taking into account both magnitude and direction.

Front

What is inertia?

Back

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

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a).

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces do.
