A soccer ball is traveling downfield with a force of 1.2 kN and strikes another soccer ball that is stationary. Which of the following describes the result of the collision?
The stationary soccer ball will begin moving upfield and the ball that struck it will slow down. The stationary soccer ball will begin moving upfield and the ball that struck it will slow down. The stationary soccer ball will begin moving downfield and the ball that struck it will accelerate. The stationary soccer ball will begin moving downfield and the ball that struck it will accelerate. The stationary soccer ball will begin moving downfield and the ball that struck it will slow down. The stationary soccer ball will begin moving downfield and the ball that struck it will slow down. Neither ball will move after impact.
The stationary soccer ball will begin moving downfield and the ball that struck it will slow down.

A car traveling northward with 5 kN of force could be brought to a stop by a southward force of 5 kg. A car traveling northward with 5 kN of force could be brought to a stop by a southward force of 5 kN. A car traveling northward with 5 kN of force could be brought to a stop by a southward force of 5 kN. A car traveling northward with 5 kN of force could be brought to a stop by a northward force of 5 kN. A car traveling northward with 5 kN of force could be brought to a stop by a northward force of 5 kN. A car traveling northward with 5 kN of force could be brought to a stop by a southward force of 10 kN.

What is force directly proportional to?
the velocity and mass of an object the velocity and mass of an object the acceleration and speed of an object the acceleration and speed of an object the acceleration and weight of an object the acceleration and weight of an object the acceleration and mass of an object
Force is directly proportional to the acceleration and mass of an object.
Two ropes are being used to suspend a box. Each rope is exerting 5 N of upward force. If the forces are balanced and the box is stationary, how much force is being exerted by the box itself and in which direction?
No forces are being exerted by the box. No forces are being exerted by the box. The box exerts 5 N of force downward. The box exerts 5 N of force downward. The box exerts 10 N of force downward. The box exerts 10 N of force downward. The box exerts 10 N of force upward.
The box exerts 10 N of force downward.
The statement that best describes force is: "Force is a vector quantity that measures both direction and magnitude of a push or pull on an object."
To understand why this is the correct statement, let's break it down:
1. Quantity: Force is a physical quantity that can be measured. It is a fundamental concept in physics.
2. Scalar vs. Vector: Scalar quantities only have magnitude (size), while vector quantities have both magnitude and direction. Since force has both magnitude (e.g., 5 Newtons) and direction (e.g., to the right), it is considered a vector quantity.
3. Push or Pull: Force can either be a push or a pull on an object. It is the interaction between two objects that causes a change in motion or deformation.
Therefore, the correct statement is that force is a vector quantity measuring both direction and magnitude of a push or pull on an object.
