Equal and Unequal Forces

Front

What are equal forces?

Back

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

Front

What are unequal forces?

Back

Unequal forces are forces that do not have the same strength, causing an object to move in the direction of the stronger force.

Front

What is gravity?

Back

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

Front

What is an example of an unbalanced force?

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

Back

Conducting multiple trials helps ensure the results are reliable and accurate.

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an example of a balanced force?

Back

An example of a balanced force is two people pushing on opposite sides of a box with equal strength.

Front

What is the effect of gravity on objects?

Back

Gravity pulls objects toward the center of the Earth, affecting their weight and motion.
