Which scientist first stated the principle of inertia?

• Galileo Galilei

• Isaac Newton

• Albert Einstein

• James Prescott Joule

Objects in a state of motion (either moving or at rest) tend to remain that way. According to Galileo is the:

• Remaining State of Motion

• Natural state of Motion

• Acceleration of Motion

• Galilei State of Motion

It's an agent that causes or opposes changes in the motion of matter, or

tends to do so.

• Weight

• Mass

• Force

• Vector

What is the symbol that represents the resultant of simultaneous concurrent forces?

• Alpha

• Beta

• Sigma

• Theta

What is the force called that exactly balances a nonzero force sum acting on an object?

• summing force

• unbalanced

• balanced force

• equilibrant force

Select the one that is not a fundamental force

• gravity

• Electroganectism

• nuclear interaction

• Friction

The sum of all forces on an object is called

• the weight vector.

• the resultant force.

• the equilibrant force.

• the reaction force.

What is the minimum number of forces that must act on a system in order to have an unbalanced force on the system?

• 1 force

• 2 forces

• 0 force

• 3 forces

What is the minimum number of forces that must act on a system in order to have a balanced force on the system?

• 1 force

• 2 forces

• 3 forces

• 0 force

According to Newton’s second law, doubling a net force on a system of constant mass will double...

• the mass

• the acceleration

• the force

• the magnitude
