Forces and Free Body Diagrams

Front

What is a force?

Back

A force is a push or pull acting upon an object as a result of its interaction with another object.

Front

What is equilibrium in the context of forces?

Back

Equilibrium occurs when the net force acting on an object is zero, resulting in no change in motion.

Front

What happens to the velocity of an object in equilibrium?

Back

The velocity remains constant if the object is already in motion.

Front

What are free body diagrams?

Back

Free body diagrams are graphical representations used to visualize the forces acting on an object.

Front

What forces act on a car moving at constant velocity?

Back

Gravity, Normal, Friction, and Applied forces act on the car.

Front

What is the force of tension in a hanging chandelier?

Back

The force of tension is equal to the force of gravity acting on the chandelier when in equilibrium.

Front

What forces does a hockey puck experience when moving at constant velocity on ice?

Back

The hockey puck experiences Gravity and Normal forces.

Front

How does mass differ from weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g).

Front

What is gravitational acceleration on Earth?

Back

Gravitational acceleration on Earth is approximately 9.81 m/s².
