Equal and Unequal Forces

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What are equal forces?

Back

Equal forces are forces that are the same in size and direction, resulting in no change in motion.

Front

What are unequal forces?

Back

Unequal forces are forces that are different in size or direction, causing an object to move or change its motion.

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 type affect force?

Back

Different surfaces create different amounts of friction, which affects the amount of force needed to move an object.

Front

What is a spring scale?

Back

A spring scale is a tool used to measure the force of gravity on an object, often in units like grams or newtons.

Front

What is an example of an unbalanced force?

Back

An example of an unbalanced force is when one person pushes a box to the right while another person pushes it to the left with less force.

Front

What happens when two equal forces act on an object in opposite directions?

Back

When two equal forces act on an object in opposite directions, they cancel each other out, and the object does not move.

Front

What is the effect of gravity on falling objects?

Back

Gravity causes all objects to fall toward the Earth at the same rate, regardless of their mass.

Front

What is the relationship between mass and force?

Back

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