What is the formula for calculating kinetic energy (KE)?

Back

KE = 0.5 * m * v^2, where m is mass in kilograms and v is velocity in meters per second.

Front

How do you convert horsepower (hp) to watts (W)?

Back

1 hp = 746 W. To convert hp to W, multiply the horsepower value by 746.

Front

What two factors does gravitational potential energy depend on?

Back

Gravitational potential energy depends on height and mass of the object.

Front

What is the velocity of an object at its highest point when thrown straight up?

Back

0 m/s.

Front

How do you calculate distance traveled given speed and time?

Back

Distance = Speed x Time.

Front

What is the unit of power in the International System of Units (SI)?

Back

The unit of power is the watt (W).

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy is directly proportional to mass; as mass increases, kinetic energy increases if velocity is constant.

Front

What is the effect of height on gravitational potential energy?

Back

Gravitational potential energy increases with height; the higher the object, the more potential energy it has.

Front

If an object is moving at a constant speed, what can be said about the net force acting on it?

Back

The net force acting on the object is zero.

Front

What is the formula for calculating gravitational potential energy (GPE)?

Back

GPE = m * g * h, where m is mass, g is acceleration due to gravity (9.8 m/s²), and h is height.
