Physics Final: proportional reasoning

Front

What is torque?

Back

Torque is a measure of the rotational force applied to an object, calculated as the product of the force and the distance from the pivot point to the line of action of the force.

Front

What is the condition for positive torque around a pivot?

Back

Positive torque occurs when the force causes a counterclockwise rotation around the pivot.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or height above the ground, calculated as PE = mgh (mass x gravity x height).

Front

How does height affect potential energy?

Back

Potential energy increases with height; doubling the height of an object will double its potential energy, assuming mass remains constant.

Front

What is projectile motion?

Back

Projectile motion is the motion of an object thrown into the air, subject to gravitational acceleration, following a curved trajectory.

Front

What are the components of projectile motion?

Back

Projectile motion can be analyzed in two components: horizontal (X) motion, which is uniform, and vertical (Y) motion, which is subject to acceleration due to gravity.

Front

What is uniform motion?

Back

Uniform motion refers to motion at a constant speed in a straight line, with no acceleration.

Front

What is the relationship between velocity and displacement?

Back

Velocity is a vector quantity that indicates the rate of change of displacement with respect to time, and it always points in the direction of displacement.

Front

What happens to the velocity of an object in free fall?

Back

In free fall, the velocity of an object increases due to the acceleration of gravity, which is approximately 9.81 m/s² downward.

Front

What is the formula for calculating potential energy?

Back

The formula for potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
