AP Physics Unit 2-3: Dynamics & Circular Motion

Front

What is a Free Body Diagram (FBD)?

Back

A graphical representation used to visualize the forces acting on an object. It shows all the forces, including their direction and magnitude.

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object, directly proportional to its mass (Weight = mass × gravity).

Front

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

Back

Net force is calculated by summing all the forces acting on the object, taking into account their directions.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) is calculated using the formula a = F/m, where F is the net force and m is the mass of the object.

Front

What is the significance of constant speed in dynamics?

Back

Constant speed indicates that the object is moving without acceleration, meaning the net force acting on it is zero.

Front

How do you determine the mass of an object using acceleration and force?

Back

Using Newton's second law, rearrange the formula F = ma to find mass: m = F/a.

Front

What is tension in a string?

Back

Tension is the force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

What factors affect the tension in a string?

Back

Tension is affected by the weight of the objects being supported, the angle of the string, and any additional forces acting on the system.

Front

What is circular motion?

Back

Circular motion is the motion of an object traveling along a circular path, requiring a net force directed towards the center of the circle.
