Same Speed
Equal forces are applied to a large truck and a motorcycle (both initially at rest) at the same time. After 5 seconds, the motorcycle is moving _(Faster, Slower, Same Speed)_than the truck.
What is the evidence for the motorcycle's motion in comparison with the truck?
The truck started with a higher force than the motorcycle.
The motorcycle started with a higher force than the truck.
The motorcycle has less mass than the truck.
The motorcycle has more mass than the truck.
Equal forces are applied to a large truck and a motorcycle (both initially at rest) at the same time. After 5 seconds, the motorcycle is moving _(Faster, Slower, Same Speed)_than the truck.
What is the reasoning for the evidence for the motorcycle's motion in comparison with the truck?
If force is constant then a lower mass means lower acceleration.
If force is constant then a higher mass means greater acceleration.
If force is constant then a lower mass means greater acceleration.
If force is constant then a lower mass means equal acceleration.
A fly meets its unfortunate end on the windshield of a moving car. When the fly hits the windshield, the force on the fly is __(Greater than, Less than, Equal to)__ to the force on the truck.
Less than

Equal to
A fly meets its unfortunate end on the windshield of a moving car. When the fly hits the windshield, the force on the fly is __(Greater than, Less than, Equal to)__ to the force on the truck.

What is the evidence for how the force on the fly in comparison to the force on the truck?
The fly is not in contact with the truck.
The fly is an illusion and there is only the truck.
The fly is in contact with the truck.
A fly meets its unfortunate end on the windshield of a moving car. When the fly hits the windshield, the force on the fly is __(Greater than, Less than, Equal to)__ to the force on the truck.

What is the reasoning for the evidence for how the force on the fly in comparison to the force on the truck?
From 3rd Law, the force of the fly is smaller in magnitude but opposite direciotn of the truck's force.
From 3rd Law, the force of the fly is greater in magnitude but opposite direction of the truck's force.
From 3rd Law, the force of the fly is equal in magnitude but opposite direction of the truck's force.
An Ice Skater is coasting along the surface of a frozen pond with constant velocity. The force needed to maintain her motion is_(Greater than zero, less than zero, zero)_.
Less than zero
Greater than zero
zero
An Ice Skater is coasting along the surface of a frozen pond with constant velocity. The force needed to maintain her motion is_(Greater than zero, less than zero, zero)_.
What is the evidence for the force needed to maintain her motion?
She is accelerating and slowing down.
She is coasting with constant velocity.
She is accelerating and speeding up.
An Ice Skater is coasting along the surface of a frozen pond with constant velocity. The force needed to maintain her motion is_(Greater than zero, less than zero, zero)_.
What is the reasoning for the evidence for the force needed to maintain her motion?
If velocity is changing then there is net acceleration, so net force needed.
If velocity is changing then there is net acceleration, so no net force needed.
If velocity is constant then there is no net acceleration, so no net force needed.
