Forces Flashcard Review

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, such as the Earth and an object, which pulls the object towards the center of the Earth.

Front

What does a free body diagram represent?

Back

A free body diagram is a graphical representation that shows all the forces acting on an object, helping to analyze the object's motion.

Front

What is a normal force?

Back

Normal force is the support force exerted upon an object that is in contact with a surface, acting perpendicular to the surface.

Front

What is the role of a supporting surface in physics?

Back

A supporting surface provides the normal force that counteracts the weight of an object resting on it.

Front

What happens to a box on a smooth horizontal table?

Back

A box at rest on a smooth horizontal table experiences balanced forces, resulting in no net force and no movement.

Front

What is the effect of friction on a moving object?

Back

Friction opposes the motion of an object, causing it to slow down or stop.

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.

Front

How does a compressed spring exert force?

Back

A compressed spring exerts a force when it tries to return to its original shape, pushing or pulling on an object.

Front

What is the significance of constant speed in motion?

Back

Constant speed means that an object is moving at the same rate over time, indicating balanced forces acting on it.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on an object at rest, preventing it from moving, while kinetic friction acts on an object in motion, slowing it down.
