Force, Motion, and Energy

What is force?

• Force is a mental concept that does not have any physical existence.

• Force is a physical quantity that can change the state of motion or shape of an object.

• Force is a form of energy that can be converted into work.

• Force is a measure of the amount of matter in an object.

Give an example of a force.

• Gravity

• Inertia

• Magnetism

• Friction

What is motion?

• Change in speed of an object over time.

• Change in shape of an object over time.

• Change in color of an object over time.

• Change in position of an object over time.

What are the three types of motion?

• linear motion, circular motion, and oscillatory motion

• random motion

• translational motion

• rotational motion

What is energy?

• Energy is the capacity to store information.

• Energy is the process of converting matter into energy.

• Energy is the force that holds atoms together.

• Energy is the ability to do work or cause change.

Name two types of energy.

• nuclear energy and chemical energy

• thermal energy and electrical energy

• solar energy and wind energy

• kinetic energy and potential energy

What is the unit of force?

• Second (s)

• Meter (m)

• Kilogram (kg)

• Newton (N)

What is the formula to calculate force?

• force = mass x acceleration

• force = mass / acceleration

• force = mass + acceleration

• force = mass - acceleration

What is the formula to calculate kinetic energy?

• KE = 1/2 * mass * velocity^2

• KE = mass * acceleration

• KE = mass * velocity^2

• KE = 1/2 * mass * acceleration^2

What is the relationship between force, mass, and acceleration?

• force = mass + acceleration

• force = mass * acceleration

• force = mass / acceleration

• force = mass - acceleration
