Forces Final Exam Practice 2024-25

Front

What is the definition of net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration.

Front

What is the formula for calculating force?

Back

F = ma, where F is force, m is mass, and a is acceleration.

Front

If an object has a mass of 10 kg and an acceleration of 2 m/s², what is the force acting on it?

Back

20 N

Front

What happens to an object if the net force acting on it is 0 N?

Back

The object will move with constant velocity.

Front

What are unbalanced forces?

Back

Unbalanced forces occur when the total forces acting on an object are not equal, causing the object to accelerate.

Front

What are the two ways to have unbalanced forces?

Back

1) Unequal forces in opposite directions, 2) Forces in the same direction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, the greater the mass of an object, the less acceleration it will have for a given force.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between surfaces.

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object; it will either remain at rest or continue moving at a constant speed.
