### The unit representing force is the __________?

Explanation

The unit representing force is the newton. The newton is the SI unit of force, named after Sir Isaac Newton. It is defined as the force required to accelerate a one-kilogram mass by one meter per second squared. The newton is commonly used to measure forces in various fields such as physics and engineering.Rate this question:

### Solve this problem. An object having a 5 kg mass and 4m/s2 acceleration will have ______ N force.

Explanation

The force exerted on an object can be calculated using the formula F = m * a, where F is the force, m is the mass, and a is the acceleration. Given that the mass is 5 kg and the acceleration is 4 m/s^2, we can substitute these values into the formula to find the force. Therefore, the force exerted on the object is 5 kg * 4 m/s^2 = 20 N.Rate this question:

### Solve this problem An object with 30kg mass and 7 m/s2 acceleration will have _____ N force.

Explanation

The force exerted on an object can be calculated using Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a). In this case, the mass of the object is given as 30kg and the acceleration is given as 7 m/s^2. Therefore, the force can be calculated as 30kg * 7 m/s^2, resulting in a force of 210 N.Rate this question:

### Solve this problem. An object with a force of 30 N and having an accerleration of 3 m/s2 will have a _______kg mass.

Explanation

The mass of an object can be calculated using the formula F = ma, where F is the force applied on the object, m is the mass of the object, and a is the acceleration of the object. Rearranging the formula, we can solve for mass: m = F/a. Given that the force is 30 N and the acceleration is 3 m/s2, we can substitute these values into the formula to find the mass: m = 30 N / 3 m/s2 = 10 kg. Therefore, the object will have a mass of 10 kg.Rate this question:

### If the same force is applied to objects of different mass, which object will have the greater acceleration?

- 14.
### (357) Forces can change the ______ of motion.

Explanation

Forces can change the direction of motion. This means that when a force is applied to an object, it can cause the object to change its path or move in a different direction than before. This is because forces can cause objects to accelerate or decelerate, leading to a change in their velocity and ultimately their direction of motion.Rate this question:

### Any ______ that keeps an object moving in a circle is known as a centripetal force.

Explanation

A centripetal force is any force that keeps an object moving in a circle. In this context, the word "centripetal" refers to the direction of the force, which is towards the center of the circle. Without this force, the object would move in a straight line tangent to the circle. Therefore, the correct answer is "force".Rate this question:
