Unit 3 Review BR

Front

What is gravitational force?

Back

A force that attracts any object.

Front

What is the formula for centripetal acceleration?

Back

Front

How does the distance from a planet affect gravitational force?

Back

Front

What is torque?

Back

Front

What is the principle of moments?

Back

For an object in equilibrium, the sum of clockwise moments about a pivot equals the sum of counterclockwise moments.

Front

What is static equilibrium?

Back

Static equilibrium occurs when an object is at rest and the net force and net torque acting on it are both zero.

Front

What is dynamic equilibrium?

Back

Dynamic equilibrium occurs when an object is moving at a constant velocity and the net force acting on it is zero.

Front

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

Back

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

Front

What is the relationship between force, mass, and acceleration?

Back

Front

What is the effect of applying force at the edge of a door?

Back

Applying force at the edge of a door far from the hinges maximizes torque, making it easier to open.
