Unit 1.1 Final Exam

Front

What is the effect of multiple forces acting on an object with no friction?

Back

The object will move in the direction of the net force acting on it.

Front

What force is increased by pouring sand on an icy road to help cars stay on the road?

Back

Friction.

Front

How does the roughness of a surface affect friction?

Back

Rough surfaces have greater friction compared to smoother surfaces.

Front

What will happen to objects of different masses dropped simultaneously from a height in a vacuum?

Back

All objects will hit the ground at the same time, regardless of their mass.

Front

What is the definition of Net Force?

Back

Net Force is the vector sum of all the forces acting on an object.

Front

What is the Net Force and the direction of movement when forces are balanced?

Back

0N, No Movement.

Front

How does friction affect the motion of an object?

Back

Friction opposes the motion of an object, slowing it down or preventing it from moving.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force acting on an object is directly proportional to its mass.

Front

What happens to the motion of an object when the net force is not zero?

Back

The object will accelerate in the direction of the net force.

Front

What is the role of friction in everyday life?

Back

Friction allows us to walk, drive, and hold objects without slipping.
