U11: Review, Inquiry

Front

What is the initial vertical speed of a cannonball fired horizontally from a height?

Back

0.00 m/s

Front

What type of force is gravitational force between two masses?

Back

The force is always attractive.

Front

If two planets have equal mass and are orbiting a star, which will orbit faster?

Back

The planet closer to the star will orbit faster.

Front

What is the relationship between mass and gravitational force?

Back

Neither mass experiences a greater force; they experience equal forces.

Front

Which planet experiences the strongest gravitational pull if all are orbiting the same star?

Back

The planet closest to the star experiences the strongest gravitational pull.

Front

What is the formula for gravitational force between two masses?

Back

F = G * (m1 * m2) / r^2, where G is the gravitational constant.

Front

What happens to the gravitational force if the distance between two masses increases?

Back

The gravitational force decreases.

Front

What is the effect of height on the gravitational potential energy of an object?

Back

Gravitational potential energy increases with height.

Front

What is the definition of gravitational acceleration on Earth?

Back

Approximately 9.81 m/s².

Front

How does mass affect the acceleration of an object under gravity?

Back

All objects accelerate at the same rate regardless of mass.
