Front

What is the horizontal component of velocity?

Back

The horizontal component of velocity is the part of the velocity vector that is parallel to the ground. It can be calculated using the formula: Vx = V * cos(θ), where V is the initial velocity and θ is the angle of projection.

Front

What is the relationship between the time taken by two objects to fall simultaneously?

Back

If two objects are released simultaneously from the same height, they will take the same amount of time to reach the ground, regardless of their mass.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It is often associated with the height of an object above the ground.

Front

What two factors affect the force of gravity between two objects?

Back

The two factors that affect the magnitude of the gravitational force between two objects are their masses and the distance between them.

Front

Which object has the most potential energy?

Back

An object at a higher position has more potential energy. For example, a car at the top of a hill has more potential energy than a car speeding down the hill.

Front

How do you calculate the horizontal component of velocity for a projectile?

Back

To calculate the horizontal component of velocity (Vx), use the formula: Vx = V * cos(θ), where V is the initial velocity and θ is the angle of projection.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated using the formula: KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in kilograms, while weight is the force exerted by gravity on that mass, measured in newtons.

Front

What is the formula for gravitational force?

Back

The formula for gravitational force (F) between two masses (m1 and m2) separated by a distance (r) is: F = G * (m1 * m2) / r², where G is the gravitational constant.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
