Forces & Interactions

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 type of friction do the wheels on a moving skateboard experience?

Back

Rolling Friction is the force that opposes the motion of an object rolling over a surface.

Front

In a tug of war, how can you determine the winner?

Back

The winner is the side with the greater net force acting in their direction.

Front

What can be said about the forces acting on a stationary object?

Back

If an object is stationary, the forces acting upon it are balanced.

Front

What type of friction acts on an object that is not yet moving?

Back

Static friction is the force that must be overcome to start moving an object at rest.

Front

What is unbalanced force?

Back

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

Front

What is kinetic friction?

Back

Kinetic friction is the force that opposes the motion of two surfaces sliding past each other.

Front

What is the role of gravity in forces and interactions?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

What is the difference between static and dynamic friction?

Back

Static friction acts on objects at rest, while dynamic (or kinetic) friction acts on objects in motion.

Front

How does mass affect the force of gravity?

Back

The force of gravity increases with the mass of the object; heavier objects experience a stronger gravitational pull.
