physics 1

• Newton's second law of motion describes how the velocity of an object changes when it is subjected to an external force.
• Newton's first law of motion states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
• the speed of light is the maximum possible velocity
• what is the difference between potential energy and kinetic energy
• inertia is an object's resistance to change its state of motion
• the speed of light is the maximum possible speed
• Newton's third law of motion states that for every action, there is an equal and opposite reaction.
• light travels at approximately 300,000 km/sec or 670 million miles per hour
• inertia is an object's resistance to change in motion
• The equation F = ma relates the net force acting on an object, its mass, and its acceleration.
• Inertia refers to the tendency of objects at rest or moving with constant speed to remain so unless acted upon by a resultant force.
• Acceleration is defined as the rate of change of velocity.
• The acceleration due to gravity on Earth is approximately 9.8 m/s^2, but can vary depending on location.
• Inertia refers to the tendency of an object to resist changes in its state of motion.
• Mass is a measure of the amount of matter in an object, while weight is a measure of the gravitational pull acting on an object.
