Types of Forces

Front

What is air resistance?

Back

Air resistance is a force that opposes the motion of an object through the air, acting in the opposite direction to the object's velocity.

Front

What force keeps a paraglider in the air?

Back

Air resistance helps to keep a paraglider in the air by counteracting the force of gravity.

Front

What is the direction of a car's velocity when rounding a bend?

Back

The direction of the car's velocity is tangential to the curve of the bend.

Front

What is centripetal force?

Back

Centripetal force is the force that acts on an object moving in a circular path, directed toward the center of the circle.

Front

What force opposes the motion of a paraglider?

Back

Air resistance opposes the motion of a paraglider.

Front

What is tension force?

Back

Tension force is the force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

How does air resistance affect the speed of a falling object?

Back

Air resistance increases with the speed of the falling object, eventually balancing the force of gravity and leading to terminal velocity.

Front

What is the relationship between centripetal force and velocity in circular motion?

Back

Centripetal force is directly proportional to the square of the velocity of the object and inversely proportional to the radius of the circular path.

Front

What role does gravity play in the motion of a paraglider?

Back

Gravity pulls the paraglider downward, while air resistance provides an upward force that helps to keep it aloft.

Front

What happens to the forces acting on an object in equilibrium?

Back

In equilibrium, the net force acting on an object is zero, meaning all forces are balanced.
