Forces and Motion Flashcard Review

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the total force acting on an object is not zero, causing the object to change its motion (speed or direction).

Front

What is a balanced force?

Back

A balanced force occurs when the total force acting on an object is zero, resulting in no change in motion.

Front

What two factors does gravity depend on?

Back

Gravity depends on mass and distance between objects.

Front

How does mass affect an object's motion?

Back

An object with greater mass requires more force to change its motion compared to an object with less mass.

Front

What is net force?

Back

Net force is the total force acting on an object, calculated by combining all individual forces acting on it.

Front

What happens to an object's motion when the net force is zero?

Back

When the net force is zero, the object remains at rest or continues to move at a constant speed in a straight line.

Front

Why can a smaller object change direction more easily than a larger object?

Back

A smaller object typically has less mass, which means it requires less force to change its direction.

Front

What is the relationship between mass and gravitational pull?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

How does distance affect gravitational force?

Back

As the distance between two objects increases, the gravitational force between them decreases.

Front

What is the effect of turbulence on an airplane's motion?

Back

Turbulence creates unbalanced forces that can change the direction of the airplane's motion.
