What is an S-Wave?

Back

S-Wave, or Secondary Wave, is a type of seismic wave that moves through the Earth and is characterized by its shear motion, which means it moves the ground up and down or side to side. S-Waves can only travel through solids.

Front

What is the formula to calculate net force?

Back

Net Force (F_net) = mass (m) × acceleration (a).

Front

What is the relationship between net force and acceleration?

Back

According to Newton's second law, the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

Front

What does a velocity of 0 indicate on a graph?

Back

A velocity of 0 indicates that the object is at rest and not moving during that time interval.

Front

What factors determine the direction of the acceleration vector?

Back

The direction of the acceleration vector is determined by the direction the object is moving and whether the object is speeding up or slowing down.

Front

What is the definition of mass in physics?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).

Front

What is a P-Wave?

Back

P-Wave, or Primary Wave, is a type of seismic wave that is the fastest and first to arrive during an earthquake. It compresses and expands the material it travels through.

Front

What does it mean if the net force on an object is zero?

Back

If the net force on an object is zero, it means that the object is either at rest or moving at a constant velocity, indicating that all forces acting on it are balanced.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time, typically measured in meters per second squared (m/s²).

Front

What is the significance of the direction of forces in physics?

Back

The direction of forces is crucial in determining the motion of an object; it affects how the object accelerates and changes its velocity.
