What is torque?
Torque is the turning effect of a force around a pivot or axis. It is what makes objects rotate.
What is the lever arm in physics?
The lever arm is the perpendicular distance from a pivot point to the line of action of a force. It determines how much torque the force produces.
What is inertial mass?
Inertial mass is a measure of how much an object resists changes in motion. The larger the inertial mass, the harder it is to accelerate or slow down the object.
What is pressure in physics?
Pressure is force applied per unit area. It is measured in pascals.
What is the center of mass?
The center of mass is the average location of all the mass in an object or system. It is the point that moves as if all the mass were concentrated there.
How do torques make a door swing open?
Torque is the turning effect of a force. Pushing far from a door hinge creates more torque than pushing near the hinge, so the door opens more easily.
