Study Guide: Lesson 1-5 Assessment

What is the definition of Force?

• A) A change in an object's shape

• B) A push or pull that can lead to an object's change in motion, measured in Newtons (N)

• C) The energy an object has when in motion

• D) A tool used to measure force

What does Deformation refer to?

• The energy an object has when in motion

• A change in an object's shape

• A tool used to measure force

• A diagram that shows all the forces acting on a single object

Kinetic Energy is defined as:

• The energy possessed by an object due to its motion

• The energy stored in an object due to its position

• The energy released during a chemical reaction

• The energy produced by nuclear reactions

What happens during a Collision?

• Objects make contact resulting in deformation and possibly a change in motion

• A push or pull that can lead to an object's change in motion

• The amount of matter in an object

• A value that has both magnitude and direction

What is a Spring Scale used for?

• To measure the amount of matter in an object

• To measure push or pull force, in Newtons (N), based on a spring

• To show all the forces acting on a single object

• To measure the energy an object has when in motion

What is Mass?

• A measure of the amount of matter in an object

• The force exerted by gravity on an object

• The volume of an object

• The density of an object

What is a Vector?

• A diagram that shows all the forces acting on a single object

• A value that has both magnitude and direction

• A tool used to measure force

• A change in an object's shape

What is a Free Body Diagram?

• A diagram showing all the forces acting on an object

• A diagram showing the internal structure of a body

• A diagram representing the energy levels of a system

• A diagram illustrating the motion path of an object

Why did Max's football travel farther? How does the kinetic energy of the football relate to how far it travels after Max’s stronger kick?

• Max's football traveled farther because it had more kinetic energy due to a faster kick.

• Max's football traveled farther because it was lighter than Emma's football.

• Max's football traveled farther because it was kicked at a higher angle.

• Max's football traveled farther because it was a newer ball.

As they observe their kicks, both Emma and Max wonder why Max's football traveled farther. What happens to the kinetic energy when Emma kicks the ball more softly, and why does the ball travel a shorter distance?

• Emma's kick had less kinetic energy, causing the ball to travel a shorter distance.

• Emma's kick had more kinetic energy, causing the ball to travel a shorter distance.

• Emma's kick had the same kinetic energy, but the ball traveled a shorter distance due to air resistance.

• Emma's kick had less kinetic energy, but the ball traveled a shorter distance due to gravity.
