Physical Science Practice Sheet
Introduction
Physical Science is the study of the physical world and how it works. This practice sheet will help you learn and understand more about Physical Science.
Section 1: Motion
- What is motion?
Motion is the change in position of an object over time.
- What are the three types of motion?
The three types of motion are: linear motion, circular motion, and oscillatory motion.
- What is acceleration?
Acceleration is the rate at which an object's speed or direction changes.
- What is the formula for calculating acceleration?
The formula for calculating acceleration is: acceleration = change in velocity/time.
Section 2: Force
- What is force?
Force is a push or pull that can cause an object to move, stop, or change direction.
- What is the formula for calculating force?
The formula for calculating force is: force = mass x acceleration.
- What are the two types of force?
The two types of force are: contact force and non-contact force.
- What is the difference between a contact force and a non-contact force?
A contact force is a force that is applied directly to an object, while a non-contact force is a force that is applied without any physical contact. Examples of contact forces include pushing, pulling, and friction, while examples of non-contact forces include gravity and magnetism.
Section 3: Energy
- What is energy?
Energy is the ability to do work.
- What are the two types of energy?
The two types of energy are kinetic energy and potential energy.
- What is the formula for calculating kinetic energy?
The formula for calculating kinetic energy is: kinetic energy = 1/2 x mass x velocity2.
- What is the formula for calculating potential energy?
The formula for calculating potential energy is: potential energy = mass x gravity x height.
