Toy Boats Force Flashcard

Front

What is force?

Back

Force is a push or pull on an object that can cause it to change its velocity (speed or direction).

Front

What is mass?

Back

Mass is the amount of matter in an object, typically measured in kilograms or grams.

Front

How does mass affect force?

Back

The greater the mass of an object, the more force is required to change its motion.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can be a change in speed or direction.

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 at a constant velocity unless acted upon by a net external force.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between two surfaces.

Front

What is the relationship between force and acceleration?

Back

According to Newton's Second Law, 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 a net force?

Back

Net force is the total force acting on an object when all the individual forces are combined.

Front

What happens when two objects collide?

Back

When two objects collide, they exert forces on each other, which can change their speeds and directions.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
