Motion and Stability Study Guide

Front

What force causes a ball to fall to the ground when it is soaring through the air?

Back

Gravity

Front

What is a balanced force?

Back

A balanced force occurs when two equal forces push or pull in opposite directions, resulting in no movement.

Front

What happens to a skateboard when the forces acting on it are unbalanced?

Back

The skateboard will move in the direction of the greater force.

Front

Define an unbalanced force.

Back

An unbalanced force occurs when one force is greater than another, causing an object to change its speed or direction.

Front

Name four forces that can affect whether a force is balanced or unbalanced.

Back

Gravity, push, pull, and friction.

Front

What is the effect of gravity on objects in motion?

Back

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

Front

How do push and pull forces affect an object's motion?

Back

Push forces move an object away, while pull forces draw an object closer, both affecting its speed and direction.

Front

What is the relationship between balanced forces and motion?

Back

Balanced forces do not cause a change in motion; the object remains at rest or continues to move at a constant speed.

Front

What is the net force when two equal forces act in opposite directions?

Back

The net force is zero, resulting in no change in motion.

Front

How does friction affect motion?

Back

Friction opposes motion, slowing down or stopping moving objects.
