Forces and Motion Study Guide

Who was known as 'the father of modern physics' and developed the 3 Laws of Motion?

• Isaac Newton

• Albert Einstein

• Galileo Galilei

• Nikola Tesla

What is the 1st law of motion (part 1) about?

• It is about the concept of inertia, stating that an object will remain at rest or in uniform motion unless acted upon by an external force.

• It is about the gravitational force that objects experience on Earth.

• It is about the relationship between energy and mass.

• It discusses the effect of friction on motion.

What is inertia according to the 1st law of motion (part 2)?

• Inertia is the property of an object to remain at rest or in uniform motion in a straight line unless acted upon by an external force, as stated in Newton's first law of motion.

• Inertia is the tendency of an object to change its motion when attractive forces are applied.

• Inertia is the property of objects to eventually come to a complete stop due to internal friction.

• Inertia is the measure of an object’s resistance to being accelerated by a force over a curved path.

What is an example of inertia?

• A book resting on a table remains at rest until moved by an external force.

• A car accelerating when the gas pedal is pressed.

• A ball thrown in the air eventually comes down.

• Water boiling in a pot continuously moves.

What is speed a measurement of?

• speed

• time

• distance

• acceleration

What is friction?

• Friction is the resistance that one surface or object encounters when moving over another.

• Friction is the force that accelerates objects in motion.

• Friction is the force that opposes gravity.

• Friction is the measure of temperature change in objects.

What is an example of friction?

• Sliding a book on a table

• A magnet attracting a nail

• Water flowing without resistance

• A remote control operating

What is gravity?

• A force that draws objects toward the center of the Earth

• Electromagnetic attraction

• A form of friction
