CO2 Dragster Physics Concepts Worksheet

Newton's Laws of Motion - First Law (Inertia): How does this law apply to a CO2 dragster?

• A CO2 dragster remains at rest until acted upon by an external force.

• A CO2 dragster accelerates indefinitely without any force.

• A CO2 dragster changes direction without any force.

• A CO2 dragster stops immediately when the force is removed.

Kinetic and Potential Energy - Kinetic Energy: How is kinetic energy related to the motion of the dragster?

• Kinetic energy is the energy of motion, so it increases as the dragster moves faster.

• Kinetic energy is unrelated to the motion of the dragster.

• Kinetic energy decreases as the dragster moves faster.

• Kinetic energy is the energy of rest, so it decreases as the dragster moves faster.

Potential Energy is defined as:

• The energy possessed by a body due to its motion

• The energy possessed by a body due to its position or state

• The energy transferred between objects

• The energy that is lost in a system

Velocity and Acceleration: How can you measure the velocity of your dragster?

• By using a speedometer

• By calculating the distance covered over time

• By measuring the drag force

• By using a stopwatch

Impulse: The CO2 cartridge provides impulse to the dragster by:

• releasing compressed gas rapidly

• heating the dragster

• slowing down the dragster

• changing the dragster's color

Newton's Laws of Motion - First Law (Inertia): What does the first law of motion state?

• An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

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

• The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

• Energy cannot be created or destroyed, only transformed.

Velocity and Acceleration: The dragster's acceleration changes over time. How does it change?

• It increases steadily.

• It decreases steadily.

• It remains constant.

• It fluctuates.

Friction - Surface Friction: Why is it important to have smooth surfaces on your dragster?

• To reduce air resistance and increase speed

• To increase friction and slow down the dragster

• To make the dragster heavier

• To improve the appearance of the dragster

Kinetic and Potential Energy - Kinetic Energy: Kinetic energy is defined as the energy possessed by an object due to its motion.

• Energy due to position

• Energy due to motion

• Energy due to temperature

• Energy due to pressure

Force: Define force.

• A push or pull upon an object resulting from the object's interaction with another object.

• The energy possessed by a body due to its motion.

• The rate of doing work.

• The ability to do work.
