Forces and Interactions

Front

What is mass?

Back

Mass is a measure of how much matter is in an object, often perceived as how heavy something is.

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, often causing it to slow down or stop.

Front

Are all metals magnetic?

Back

No, not all metals are magnetic; only certain metals, like iron, cobalt, and nickel, exhibit magnetic properties.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

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 an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate, change direction, or change its state of motion.

Front

What is the role of gravity in forces and interactions?

Back

Gravity is a force that attracts two bodies toward each other, affecting their motion and weight.

Front

What is the formula for calculating force?

Back

Force is calculated using the formula F = m * a, where F is force, m is mass, and a is acceleration.
