Forces and Motion Review

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

What is an applied force?

Back

An applied force is a force that is applied to an object by a person or another object.

Front

What is a tension force?

Back

A tension force is a force that is transmitted through a cable, rope, wire, or string when it is pulled tight by forces acting from opposite ends.

Front

What is a normal force?

Back

A normal force is the force exerted by a surface that supports the weight of an object resting on it, acting perpendicular to the surface.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it is in contact with another surface.

Front

What happens to an object when balanced forces act on it?

Back

When balanced forces act on an object, it remains at rest or continues to move at a constant velocity.

Front

What happens to an object when unbalanced forces act on it?

Back

When unbalanced forces act on an object, it accelerates in the direction of the net force.

Front

What is the relationship between force and motion?

Back

Force is required to change the motion of an object; without force, an object will maintain its state of rest or uniform motion.
