Work

Front

What is work in physics?

Back

Work is defined as the force exerted on an object multiplied by the distance the object moves in the direction of the force.

Front

When is work done?

Back

Work is done when a force causes an object to move a distance.

Front

What is the formula for calculating work?

Back

Work (W) = Force (F) x Distance (d) x cos(θ), where θ is the angle between the force and the direction of motion.

Front

What is the unit of work?

Back

The unit of work is the Joule (J).

Front

What is the relationship between work and energy?

Back

Work is a transfer of energy. When work is done on an object, energy is transferred to that object.

Front

Is holding a heavy bag considered work?

Back

No, holding a heavy bag is not considered work because there is no movement of the bag.

Front

What is power in relation to work?

Back

Power is the rate at which work is done, measured in Watts (W).

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in grams (g), while weight is the force of gravity acting on that mass, measured in Newtons (N).

Front

What is a Newton?

Back

A Newton (N) is the unit of force in the International System of Units (SI). It is defined as the force required to accelerate a 1 kg mass by 1 m/s².

Front

What is the significance of the angle in the work formula?

Back

The angle (θ) in the work formula determines how much of the force contributes to the work done in the direction of motion.
