Force and Motion

Front

What is a force?

Back

A force is a push or pull that is exerted on matter.

Front

What happens when you apply more force to an object?

Back

The object is more likely to move or accelerate.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

How does mass affect the force needed to move an object?

Back

More mass requires more force to move the object.

Front

What is the role of gravity in motion?

Back

Gravity pulls objects toward the Earth, affecting their motion.

Front

What is the difference between static and kinetic friction?

Back

Static friction prevents motion, while kinetic friction acts on moving objects.

Front

How can you increase the force of friction?

Back

By increasing the weight of the object or using materials with higher friction.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.
