The units for momentum are:
Michael Phelps (who has a mass of 98 kg) is swimming 2.5 m/s in a lake. He gets passed by a canoe (mass = 55 kg) moving at 2 m/s.
What is Michael Phelps' momentum? (must include units)
What is the momentum of the canoe? (must include units)
How fast would the canoe have to move to have the same momentum as Michael Phelps?
(must include units)
A watermelon (1.5 kg) is falling with 13.5 kgm/s of momentum downwards. What is its velocity?
A giant hockey puck (mass = 0.8 kg) is sliding across the ice at 1.7 m/s.
What is the initial momentum of the puck?
(must include units)
A player then pushes it with their stick until it reaches a speed of 3.4 m/s. What is the new momentum of the puck?
By how much did the puck's momentum change?
(must include units)
An object at rest still has momentum due to its mass
Momentum is a vector, because it has velocity in its equation, and velocity is a vector
