Gravity and Inertia Review

Gravitational Force

• The force that repels objects away from each other.

• The force that attracts all objects toward each other.

• The force that keeps objects in motion indefinitely.

• The force that acts only on objects with mass.

What two factors affect the strength of gravity?

• Mass and distance.

• Speed and velocity.

• Temperature and pressure.

• Time and space.

What is gravity?

• A force that pulls objects toward each other.

• A type of energy that repels objects.

• A phenomenon that occurs only on Earth.

• A measure of the weight of an object.

What is the role of gravity in our solar system?

• It keeps planets in orbit around the sun.

• It causes seasons to change on Earth.

• It pulls comets towards the sun.

• It creates tides in the oceans.

Inertia

• The tendency of an object to resist a change in its motion.

• The force that causes an object to move in a circular path.

• The speed of an object in a straight line.

• The energy stored in an object due to its position.

What is an example of gravity in action?

• An apple falling from a tree.

• A balloon rising in the air.

• A bird flying in the sky.

• A leaf floating on water.

What is weight?

• The force of gravity acting on an object's mass.

• The mass of an object without gravity.

• The total amount of matter in an object.

• The resistance of an object to acceleration.

Larger masses have a __________ gravitational force.

• Weaker gravitational force.

• Stronger gravitational force.

• No gravitational force.

• Variable gravitational force.

What is the effect of distance on gravitational force?

• As distance increases, gravitational force decreases.

• As distance increases, gravitational force increases.

• Distance has no effect on gravitational force.

• Gravitational force is only affected by mass, not distance.

What is the relationship between mass and gravity?

• More mass means stronger gravitational attraction.

• More mass means weaker gravitational attraction.

• Mass has no effect on gravitational attraction.

• Gravity is independent of mass.
