Force and Motion

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion continues in motion at a constant velocity unless acted upon by an external force.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces come into contact with each other.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg). It does not change regardless of the object's location.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as Weight = Mass x Gravitational Acceleration (9.8 m/s² on Earth).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law of motion, the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

Front

What is the role of gravity in motion?

Back

Gravity is a force that attracts two bodies towards each other. It affects the motion of objects, causing them to fall towards the Earth.

Front

What is a push or pull?

Back

A push or pull is a force exerted on an object. It can cause the object to move, stop, or change direction.

Front

What happens during a head-on collision?

Back

In a head-on collision, an object in motion continues to move forward due to inertia, unless acted upon by another force.
