8.1 Unit Final Assessment Review

Front

What is a force that opposes motion?

Back

Friction is a force that opposes the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.

Front

What is the maximum force an object or system can tolerate before permanent deformation?

Back

The peak force is the maximum force that an object can withstand before it undergoes permanent deformation.

Front

What unit is used to measure force?

Back

The unit used to measure force is the Newton (N).

Front

Before the cart launches, which object has kinetic energy?

Back

The launcher has kinetic energy before the cart launches.

Front

What term describes when two things hit each other?

Back

Collision is the event that occurs when two or more bodies exert forces on each other for a relatively short time.

Front

What is kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or configuration, such as gravitational potential energy.

Front

What is air resistance?

Back

Air resistance is a type of friction that acts against the motion of an object moving through the air.

Front

What is the elastic limit?

Back

The elastic limit is the maximum extent to which a solid may be stretched without permanent alteration of size or shape.

Front

What is the difference between elastic force and peak force?

Back

Elastic force is the force exerted by a material when it is deformed, while peak force is the maximum force before permanent deformation occurs.
