Equal and Unequal Forces

Front

What are equal forces?

Back

Equal forces are forces that have the same magnitude but act in opposite directions, resulting in no change in motion.

Front

What are unequal forces?

Back

Unequal forces are forces that have different magnitudes, causing an object to accelerate in the direction of the greater force.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it is in contact with another surface.

Front

How does surface texture affect force?

Back

Different surface textures create varying amounts of friction, which affects the amount of force needed to move an object.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in grams or kilograms.

Front

How does mass affect force needed to move an object?

Back

The greater the mass of an object, the more force is required to move it.

Front

What is a spring scale?

Back

A spring scale is a tool used to measure force or weight by the distance a spring stretches.

Front

What is the relationship between force and motion?

Back

A force applied to an object can cause it to start moving, stop moving, or change direction.

Front

What is an experiment?

Back

An experiment is a scientific procedure undertaken to test a hypothesis or demonstrate a known fact.

Front

What is the purpose of conducting multiple trials in an experiment?

Back

Conducting multiple trials helps ensure the results are reliable and reduces the impact of errors.
