Understanding Motion: Position, Velocity, and Acceleration

What is the purpose of the experiment discussed in the video?

• To find the mass of a hockey puck

• To experimentally determine the position, velocity, and acceleration of a sliding puck

• To measure the temperature of the ice

• To determine the color of a hockey puck

How does the velocity of the puck change over time according to the video?

• It starts negative and increases to zero

• It remains constant throughout

• It starts positive and decreases to zero

• It fluctuates randomly

Why is the velocity of the puck considered negative?

• Because the puck is moving to the left

• Because the puck is moving to the right

• Because the puck is moving upwards

• Because the puck is stationary

What does a constant slope in the velocity-time graph indicate?

• The puck is accelerating uniformly

• The puck is decelerating

• The puck is at rest

• The puck is moving in a circle

Why is the acceleration graph a horizontal line above the time axis?

• Because the puck is speeding up

• Because the puck is moving at a constant speed

• Because the puck is not moving

• Because the puck is slowing down with positive acceleration
