- Meter, the unit of distance
- Meter, the unit of kilogram
Which of the following statements is TRUE?
- If you throw an object, it will continue at the same speed forever unless something acts to stop it.
- If you throw an object, it will continue to move because of inertia, regardless of outside forces.
- If you throw an object, it will stop when it runs out of inertia.
- If you throw an object, it will accelerate in the direction thrown.
- If you throw an object, it will eventually come to a natural stop always.
A truck hits a speck of dust. Which statement is TRUE during the collision?
- They exert equal and opposite forces on each other.
- The truck experiences much less force than the speck of dust.
- They experience the same acceleration as each other.
- The speck of dust exerts a small force, but the truck exerts a large one.
- The speck of dust accelerates, but the truck decelerates. The magnitude of the acceleration and deceleration are the same.
Which of the following best explains the unit of force?
- (kg)(m/s²), since force is mass times acceleration.
- (kg)(m/s²), since force is mass times velocity.
- (kg∙m/s), since force is mass times velocity.
- (kg∙m/s), since force is mass times acceleration.
- (kg)(m/s²)², since force is mass times acceleration and must be equal and opposite always.
