A motorcycle goes north at 40 miles per hour. A car goes south at 40 miles per hour on the same street. Which statement is true? (1 point)
O The vehicles have the same speed and velocity.
• The vehicles are going in opposite directions, so their speed is not the same.
• The vehicles have the same velocity, but not the same speed.
• The vehicles have the same speed, but different velocity.
• The vehicles have the same speed, but different velocity.
To determine which statement is true, we need to understand the concepts of speed and velocity.
Speed refers to the rate at which an object is moving, typically measured in distance per unit of time (such as miles per hour).
Velocity, on the other hand, includes both the speed and the direction of motion. It is a vector quantity, meaning it has both magnitude (the speed) and direction (north, south, east, west, etc.).
In this scenario, both the motorcycle and the car are moving at the same speed of 40 miles per hour. However, they are moving in opposite directions – the motorcycle is going north and the car is going south.
Since velocity takes into account both speed and direction, we can conclude that the vehicles have the same speed (40 miles per hour), but different velocities.
Therefore, the correct statement is:
• The vehicles have the same speed, but different velocity.
The correct statement is: The vehicles are going in opposite directions, so their speed is not the same.
What do unbalanced forces do? (1 point)
• Unbalanced forces cannot change an object's direction.
O Unbalanced forces allow an object's motion to stay the same.
• Unbalanced forces can make an object move in the opposite direction of the force that is applied.
O Unbalanced forces cause an object's motion to change.
