Fast Facts Flashcard: Dynamics

Front

On an incline of angle Θ, the perpendicular component of weight is equal to __________.

Back

mgcosΘ

Front

The __________ on an object is the single force that could replace all the individual forces acting on an object and produce the same effect.

Back

net force

Front

__________ friction is the friction force when something is moving along the surface and acts opposite the direction of motion.

Back

kinetic

Front

Newton's second law states that __________ is equal to the force experienced by an object divided by its mass.

Back

acceleration

Front

The __________ is the force of a surface on an object running perpendicular to the surface.

Back

normal force

Front

What is the formula for calculating net force when multiple forces are acting on an object?

Back

Net Force = F1 + F2 + F3 + ... (vector sum of all forces)

Front

Define inertia in the context of Newton's first law of motion.

Back

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

Front

What is the relationship between mass and weight?

Back

Weight = mass × gravitational acceleration (W = mg)

Front

What does the coefficient of friction represent?

Back

The coefficient of friction is a numerical value that represents the frictional force between two surfaces.

Front

Explain the difference between static and kinetic friction.

Back

Static friction acts on an object at rest, while kinetic friction acts on an object in motion.
