6 PM - Forces and Motion LC3 (3rd law with collisions)

What is Newton's THIRD law of motion?

• Force = mass multiplied by acceleration

• For every action, there is an EQUAL and OPPOSITE reaction.

• A body at rest will remain at rest, UNLESS acted on by an unbalanced force.

• A body in motion will remain in motion, UNLESS acted on by an unbalanced force.

The black car and the bus were in a collision and they applied EQUAL FORCES on each other.

• True

• False

Newton's Third law of motion is that for every action, there is an EQUAL and OPPOSITE reaction. What is the ACTION in this collision?

• The black car and the bus WERE MOVING

• The black car and the bus WERE AT REST.

• The black car was pushed backwards and had a lot of damage. The bus had bumper damage.

• The black car and the bus accelerated in the same direction with unequal forces when they collided.

• The black car and the bus accelerated in the same direction with unequal forces when they collided.

Newton's third law of motion is DISPROVEN in this example because the car had a lot of damage but the bus only had minor damage.

• True

• False

True or False. In the collision, the bus and car exerted an EQUAL amount of force on each other. The difference in the damage is a result of the different masses of the vehicles. (Mass is the amount of matter in an object and is similar to weight.)

• True

• False

In the collision, the bus and car exerted an EQUAL amount of force on each other. The difference in the damage is a result of the different masses of the vehicles.

What is the impact on the bus compared to the car?

• The bus experienced the SAME amount of force but had MORE mass as the car, so it had LESS damage.

• The bus experienced DIFFERENT amounts of force but had the SAME mass as the car, so it had the SAME damage.

In the collision, the bus and car exerted an EQUAL amount of force on each other. The difference in the damage is a result of the different masses of the vehicles.

What is the impact on the CAR?

• The CAR experienced the SAME amount of force as the bus but had MORE mass than the bus, so it had the SAME damage.

• The CAR experienced the SAME amount of force as the bus but had LESS mass than the bus, so it had the SAME damage.

• The CAR experienced the SAME amount of force as the bus but had LESS mass than the bus, so it had MORE damage.

True or False. Even though there is more damage to the car than the bus, each vehicle still exerts an EQUAL amount of force on the other, PROVING Newton's Third Law of motion (for every action, there is an equal and opposite reaction).

• True

• False
