Section 3 Flashcard Review on Forces

Front

What type of friction occurs when an object is NOT moving?

Back

Static Friction: The force that resists the initiation of sliding motion between two surfaces that are in contact and at rest.

Front

What is an object 'in' when the forces are balanced?

Back

Equilibrium: A state in which opposing forces or influences are balanced, resulting in no net force acting on an object.

Front

What is the SI unit for force?

Back

Newtons: The unit of force in the International System of Units (SI), defined as the force required to accelerate a one-kilogram mass by one meter per second squared.

Front

What force acts on all objects with mass in the universe?

Back

Gravitational Force: The attractive force that acts between any two masses, pulling them toward each other.

Front

What causes acceleration?

Back

Unbalanced Forces: When the total forces acting on an object are not equal, resulting in a change in the object's velocity.

Front

What is Kinetic Friction?

Back

Kinetic Friction: The force that opposes the motion of two surfaces sliding past each other.

Front

What is Fluid Friction?

Back

Fluid Friction: The resistance encountered by an object moving through a fluid (liquid or gas).

Front

What is Rolling Friction?

Back

Rolling Friction: The force that resists the motion of a rolling object on a surface.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational Force increases with mass: The greater the mass of an object, the stronger the gravitational force acting on it.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m*a) : This formula shows that force is the product of an object's mass and its acceleration.
