REVIEW Assignment

Front

What does a constant velocity p vs t graph look like?

Back

A constant velocity p vs t graph is a straight line with a constant slope.

Front

How do you calculate work done by an external force?

Back

Work done = Change in kinetic energy = Final kinetic energy - Initial kinetic energy.

Front

What is displacement?

Back

Displacement is the change in position of an object and is a vector quantity.

Front

How is mechanical energy conserved in a system?

Back

Mechanical energy is conserved when the sum of potential and kinetic energy remains constant in the absence of external forces.

Front

What is kinetic energy and how is it calculated?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or configuration, commonly gravitational potential energy.

Front

How do you determine which object has the most kinetic energy?

Back

Compare the kinetic energy of each object using the formula KE = 1/2 mv².

Front

What is the relationship between work and energy?

Back

Work done on an object results in a change in its energy.

Front

What is the formula for calculating displacement from a velocity-time graph?

Back

Displacement is the area under the velocity-time graph.

Front

What is the significance of the slope in a p vs t graph?

Back

The slope of a p vs t graph represents the velocity of the object.
