Forces

Front

What is the principle that explains why a cannonball reaches greater speeds than the cannon when fired?

Back

The explosion inside the cannon produced the same force on both objects, but the masses of the objects are different.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion, either by accelerating or decelerating.

Front

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

Back

An object in motion will stay in motion at a constant velocity.

Front

What does Fg stand for in physics?

Back

Fg stands for force of gravity, or gravitational force.

Front

What does it mean if Fnet ≠ 0?

Back

If Fnet ≠ 0, the forces acting on an object are unbalanced.

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 at a constant velocity unless acted upon by an unbalanced force.

Front

What is the relationship between mass and acceleration in the context of force?

Back

According to Newton's Second Law, acceleration is inversely proportional to mass when the same force is applied.

Front

What is the formula for calculating force?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not cause a change in motion, while unbalanced forces do.
