Newton Laws & Free Body Diagrams

Front

What is the normal force?

Back

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

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object, determining its acceleration.

Front

What happens to an object's velocity when a force is applied?

Back

When a force is applied to an object, its velocity will change, resulting in acceleration.

Front

What does the length of an arrow in a free body diagram represent?

Back

The length of the arrow represents the magnitude of the force.

Front

What does 'v' typically represent in physics?

Back

In physics, 'v' typically represents velocity.

Front

What is inertia?

Back

Inertia is the property of an object to resist changes in its state of motion.

Front

What is frictional force?

Back

Frictional force is the force that opposes the relative motion of two surfaces in contact.

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

What is weight force?

Back

Weight force is the force exerted on an object due to gravity, calculated as the mass of the object multiplied by the acceleration due to gravity.

Front

How do you calculate net force when multiple forces are acting on an object?

Back

To calculate net force, sum all the forces acting on the object, taking into account their directions.
