Newton's Laws of Motion

What does Newton's First Law of Motion state?

• An object at rest will remain at rest unless acted on by an unbalanced force.

• The acceleration of an object depends on its mass and the force applied.

• The force of gravity acts between all masses.

• For every action, there is an equal and opposite reaction.

Which of the following is an example of inertia?

• The motion of lift from an airfoil.

• An aircraft's motion resulting from aerodynamic forces.

• A jet engine producing thrust.

• A car accelerating and then hitting a wall.

What does Newton's second law state?

• An object will stay at rest unless a force is acted on it

• An object speeds up due to the force acting on it

• For every action there is an equal and opposite reaction

According to Newton's Second Law, what is the relationship between force, mass, and acceleration? (/ = Divide, * = Multiply)

• F = m + a

• F = m * a

• F = m / a

• F = a / m

What is a vector quantity?

• A quantity with only direction.

• A quantity with neither magnitude nor direction.

• A quantity with both magnitude and direction.

• A quantity with only magnitude.

What does Newton's Third Law of Motion state?

• For every action, there is an equal and opposite reaction.

• The force of gravity acts between all masses.

• An object at rest will remain at rest unless acted on by an unbalanced force.

• The acceleration of an object depends on its mass and the force applied.

Which of the following is an example of Newton's Third Law?

• The motion of a kite when the wind changes.

• A ball falling down through the atmosphere.

• The motion of a spinning ball.

• An aircraft's motion resulting from aerodynamic forces.

What is an example of Newton's second law?

• A ball being stopped by a persons foot.

• A 15 kg object at rest remains stationary without any force applied.
• An object falling freely

• A ball being kicked in a specific direction

What is the tendency of an object to resist changes in its state of motion called?

• Force

• Momentum

• Acceleration

• Inertia

Which of the following best describes the concept of force?

• The speed of an object in a specific direction

• A push or pull acting upon an object

• The resistance of an object to change its state of motion

• The energy stored in an object due to its position
