Unit 3 Remediation: Forces and Newton's Laws

Front

What is the formula to calculate the maximum static frictional force?

Back

Maximum static frictional force (F_s) = μ_s * N, where μ_s is the coefficient of static friction and N is the normal force.

Front

What is the coefficient of static friction?

Back

The coefficient of static friction (μ_s) is a dimensionless value that represents the ratio of the maximum static frictional force between two surfaces to the normal force acting on them.

Front

How do you calculate the gravitational force acting parallel to an inclined plane?

Back

Gravitational force parallel (F_parallel) = m * g * sin(θ), where m is mass, g is acceleration due to gravity, and θ is the angle of the incline.

Front

What is inertia?

Back

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

Front

What is the normal force?

Back

The normal force (N) is the force exerted by a surface that supports the weight of an object resting on it, acting perpendicular to the surface.

Front

What is the formula for calculating the net force acting on an object?

Back

Net force (F_net) = mass (m) * acceleration (a), according to Newton's second law of motion.

Front

What is Newton's first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by a net external force.

Front

What is the role of friction in motion?

Back

Friction is a force that opposes the relative motion of two surfaces in contact, acting parallel to the surfaces.

Front

How does the angle of an inclined plane affect the forces acting on an object?

Back

As the angle of the inclined plane increases, the component of gravitational force acting parallel to the plane increases, while the normal force decreases.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on an object at rest and prevents it from starting to move, while kinetic friction acts on an object in motion and opposes its movement.
