Forces and Motion Flashcard Review

Front

What is a force?

Back

A force is an action exerted on a body in order to change the body's state of motion.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is mass?

Back

Mass is the amount of matter in an object, which affects how much force is needed to move it.

Front

What is inertia?

Back

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

Front

How does friction affect motion?

Back

Friction is a force that opposes motion, making it harder for objects to move.

Front

What happens when you apply a greater force to an object?

Back

The object will accelerate and move faster.

Front

Why do heavier objects require more force to move?

Back

Heavier objects have more mass, which requires more force to overcome inertia.

Front

What is the effect of gravity on a stationary object on Earth?

Back

Gravity keeps the object in place by pulling it toward the center of the Earth.

Front

What is an example of a force that causes an object to move?

Back

Gravity is an example of a force that causes objects to move.
