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, often caused by the contact between surfaces.

Front

How does surface texture affect friction?

Back

Rough surfaces create more friction than smooth surfaces, making it harder to move objects.

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 needed 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 the effect of pulling and pushing on an object?

Back

Pulling or pushing an object applies a force that can change its position or speed.

Front

What is an experiment?

Back

An experiment is a scientific procedure to test a hypothesis by collecting data.
