Force Review

Front

What is the formula for Hooke's Law?

Back

F = kx, where F is the force applied, k is the spring constant, and x is the displacement of the spring.

Front

Define spring constant.

Back

The spring constant (k) is a measure of a spring's stiffness, defined as the force required to stretch or compress the spring by a unit distance.

Front

What is net force?

Back

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

Front

How do you calculate the component of weight perpendicular to an incline?

Back

W_perpendicular = W * cos(θ), where W is the weight and θ is the angle of the incline.

Front

What is the relationship between mass, weight, and gravity?

Back

Weight (W) is the force due to gravity acting on an object, calculated as W = mg, where m is mass and g is the acceleration due to gravity.

Front

Explain the concept of acceleration in circular motion.

Back

In circular motion, acceleration is directed towards the center of the circle and is called centripetal acceleration, which changes the direction of the velocity.

Front

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

Back

F_net = W * sin(θ), where W is the weight of the object and θ is the angle of the incline.

Front

Define frictionless ramp.

Back

A frictionless ramp is an idealized surface where no frictional force opposes the motion of an object sliding down.

Front

What does it mean for an object to move at constant speed in a circle?

Back

It means the object maintains a steady speed while continuously changing direction, resulting in centripetal acceleration.

Front

How do you determine the spring constant from a force vs. displacement graph?

Back

The spring constant (k) is the slope of the linear portion of the graph, calculated as k = F/x.
