Friction, Forces, and Newton's Laws

Front

What is net force?

Back

Net force is a combination of all forces acting on an object.

Front

What type of force keeps an object at rest or moving at a constant speed in a straight line?

Back

Balanced force.

Front

What happens when two teams pull with the same amount of force?

Back

They will not move at all.

Front

What is the force that causes an object to slow down when it touches another object?

Back

Friction.

Front

What type of friction occurs when an object is not moving?

Back

Static friction.

Front

What is the force that pulls objects toward each other, such as an apple falling to the ground?

Back

Gravity.

Front

What is inertia?

Back

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

Front

What is the difference between static friction and sliding friction?

Back

Static friction acts on objects at rest, while sliding friction acts on objects in motion.

Front

What is an unbalanced force?

Back

An unbalanced force causes an object to accelerate or change its motion.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).
