Two people are in a rowboat on a river. The current of the river water carries them at a speed of five meters per second even when they are not rowing. What will happen to the boat's motion of no other forces act on the boat?(1 point) Responses The boat's speed will increase. The boat's speed will increase. The boat's speed will decrease. The boat's speed will decrease. The boat's speed will stay the same. The boat's speed will stay the same. The boat will change direction.
Inertia is(1 point) Responses a force that acts on a resting object. a force that acts on a resting object. an object's motion. an object's motion. a moving object's speed and direction. a moving object's speed and direction. the resistance of an object to change its motio
the resistance of an object to change its motion
You are sitting in a stopped bus. When the bus starts moving forward, you appear to move backward relative to the bus. Which statement best explains this observation?(1 point) Responses Inertia prevents the force of the bus from acting on you. Inertia prevents the force of the bus from acting on you. The motion of the bus creates an unbalanced backward force on you. The motion of the bus creates an unbalanced backward force on you. The bus moves forward, while inertia keep you in place. The bus moves forward, while inertia keep you in place. The force of inertia on you balances the force from the motion of the bus.
The bus moves forward, while inertia keeps you in place.
Which statement best explains why a paper airplane eventually falls to the ground?(1 point) Responses Inertia acts as a balanced force that slows the airplane and pulls it down. Inertia acts as a balanced force that slows the airplane and pulls it down. The force from throwing the airplane loses strength as the airplane moves. The force from throwing the airplane loses strength as the airplane moves. Inertia creates the new forces acting on the airplane to keep it up. Inertia creates the new forces acting on the airplane to keep it up. The unbalanced forces of air resistance and gravity slow the airplane and pull it down.
The unbalanced forces of air resistance and gravity slow the airplane and pull it down.
