Force and Motion

Front

What is momentum?

Back

Momentum describes how much force is needed to change an object's motion.

Front

What is inertia?

Back

Inertia is the resistance to change in motion.

Front

What is the acceleration due to gravity?

Back

The acceleration due to gravity is approximately 9.8 m/s².

Front

What happens to an object in free fall?

Back

An object in free fall accelerates downwards due to gravity, increasing its speed until it reaches terminal velocity.

Front

What is the relationship between force and acceleration?

Back

Greater the acceleration, greater the force applied to an object.

Front

What factors affect air resistance?

Back

Air resistance is affected by speed, size, and shape of the object.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = m × a).

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed an object reaches when the force of gravity is balanced by air resistance.

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 the principle of conservation of momentum?

Back

The total momentum of a closed system remains constant if no external forces act on it.
