Skater 1 experiences a greater change in momentum
Skater 1 has a greater velocity than Skater 2
Skater 2 experiences a greater change in momentum
Skater 1 experiences a greater force

During a collision _______________ is always constant
Force
Motion
Momentum
Velocity
Which object listed below has the greatest momentum?
A 0.05 kg object rolling at 0.2 m/s.
A 0.15 kg object rolling at 2 m/s.
A 0.15 kg object rolling at 1 m/s

Newton's third law is about
Force and Inertia
Change in momentum
Inertia at reactions
action and reaction
If net force on an object is zero. it is considered to be
at rest
having balanced force
having unbalanced force
at motion
When two objects collide
p1>p2
p1<p2
p1 = p2
p1 * p2 = p1 + p2
When a cannon fires a cannonball we observe Newton's third law. Which force is the reaction force?
The cannon moving backward
The cannon moving forward
The cannonball moving forward
The cannonball moving backward
A baseball bat hits a baseball with a force of 100 Newtons. What is the force and its direction exerted by the ball on the bat?
same direction 100N
same direction 200N
opposite direction 100N
opposite direction 200N
A person steps out of the boat and onto the dock. As the person moves forward onto the dock, the boat moves backward. Which statement best describes the backward motion of the boat as the person steps forward?
A object is at rest or motion till an unbalance force acts on it
Momentum before and after collision are same
Force is product of mass and acceleration
Every action has equal and opposite reaction
Identify the true statement for the image
Inertia of rest is more than that of motion
Weight is does not affect inertia
