Honors Physics forces

Front

What is a force diagram (Free Body Diagram)?

Back

A graphical representation showing all the forces acting on an object, illustrating the direction and magnitude of each force.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = Net Force (F) / Mass (m).

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

What is the normal force?

Back

The force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

How do you calculate the net force acting on an object?

Back

Net Force = Sum of all forces acting on the object, taking direction into account.

Front

What is friction?

Back

A resistive force that opposes the motion of an object, acting parallel to the surfaces in contact.

Front

What is tension in a rope?

Back

The force transmitted through a rope or string when it is pulled tight by forces acting from opposite ends.

Front

What is the relationship between mass and weight?

Back

Weight (W) = Mass (m) x Gravitational Acceleration (g), where g is approximately 9.81 m/s² on Earth.

Front

What is the significance of the direction of forces in a Free Body Diagram?

Back

The direction of forces indicates how they affect the motion of the object; forces in opposite directions can cancel each other out.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on an object at rest, preventing it from starting to move, while kinetic friction acts on an object in motion.
