If a force of 50N acts on a 5 kg object, its acceleration is equal to ______ meters per second squared.
-
55
-
45
-
250
-
10
Correct Answer
A. 10Explanation
The acceleration of an object is equal to the force acting on it divided by its mass. In this case, the force acting on the 5 kg object is 50N. Dividing 50N by 5 kg gives us an acceleration of 10 meters per second squared.Rate this question:

A body at rest tends to stay at rest is called _______________,
-
Equilibrium
-
Newton's first law
-
Newton's second law
-
Newton's third law
Correct Answer
A. Newton's first lawExplanation
Newton's first law states that a body at rest tends to stay at rest, and a body in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force. This law is also known as the law of inertia. It explains the concept of equilibrium, where an object will remain in its current state unless a force is applied to it. Therefore, the correct answer is Newton's first law.Rate this question:

To find the horizontal force acting on an object that is being pulled by a rope at an angle of 50 degrees with the ground, you would use ______________.
-
The Pythagorean theorem
-
Sine
-
Cosine
-
Tangent
Correct Answer
A. CosineExplanation
To find the horizontal force acting on an object being pulled by a rope at an angle of 50 degrees with the ground, we would use cosine. The cosine function relates the adjacent side of a right triangle to the hypotenuse. In this case, the adjacent side represents the horizontal force we are trying to find, and the hypotenuse represents the total force being applied by the rope. By using cosine, we can calculate the horizontal force accurately.Rate this question:

The resistance an object has to a change in its motion is called ______________,
-
Equilbrium
-
Inertia
-
Momentum
-
Drag
Correct Answer
A. InertiaExplanation
Inertia is the correct answer because it refers to the resistance an object has to a change in its motion. This means that an object at rest will stay at rest, and an object in motion will continue moving at a constant velocity unless acted upon by an external force. Inertia is a property of matter and is directly related to an object's mass. The greater the mass, the greater the inertia, and the more difficult it is to change the object's motion.Rate this question:
