Dynamics 2

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

Define acceleration in the context of dynamics.

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

Explain the concept of friction.

Back

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

Front

What factors affect the force of friction?

Back

The force of friction depends on the normal force and the coefficient of friction between the surfaces.

Front

What is the role of mass in dynamics?

Back

Mass is a measure of the amount of matter in an object and affects its inertia and gravitational force.

Front

How does the angle of applied force affect friction?

Back

Decreasing the angle of the applied force increases the normal force, which increases friction.

Front

What is kinetic friction?

Back

Kinetic friction is the frictional force acting between moving surfaces.

Front

What is the difference between static and kinetic friction?

Back

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

Front

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

Back

Net force is the vector sum of all forces acting on an object.
