Physics Multiple Choice Concepts

Front

What is the relationship between mass and force required to accelerate an object?

Back

Generally, the more mass an object has, the more force it requires to accelerate.

Front

What is the unit of measurement for mass?

Back

Kilograms (kg)

Front

How is impulse calculated?

Back

Impulse is calculated by multiplying force by the time duration of the force applied.

Front

What happens to pressure when standing on one leg compared to two legs?

Back

Pressure increases when standing on one leg because the force is concentrated on a smaller area.

Front

Does mass change when moving from Earth to the Moon?

Back

No, mass remains the same regardless of location; weight changes due to differences in gravity.

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.

Front

What is the definition of pressure in physics?

Back

Pressure is defined as force per unit area (P = F/A).

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.

Front

How does increasing the area of contact affect pressure?

Back

Increasing the area of contact decreases pressure, as pressure is inversely proportional to area.
