assume there are two forces pushing a ball in the same direction: the first force is 5 n and the second force is 10 n. what is the total force being exerted on the ball?
5 n
15 n
20 n
10 n

Explanation:

Question 1

According to the definition of force, force is indeed a push or pull exerted on an object.

When a ball is sitting still on a table, it is in a state of equilibrium. The force of gravity pulling it downwards is balanced by the normal force exerted by the table upwards. So the forces acting on it are balanced.

When two forces act in the same direction, the total force is the sum of the individual forces. Here, \(F_{total}=F_1 + F_2\), where \(F_1 = 5N\) and \(F_2=10N\).

Step - by - Step Format:

Step1: Calculate the total force

\(F_{total}=5N + 10N\)

Step2: Simplify the expression

\(F_{total}=15N\)

Answer:

True
