What is Kinetic Energy?

Back

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

Front

How do you calculate the speed of an object using kinetic energy?

Back

Speed can be calculated using the formula v = √(2KE/m), where KE is kinetic energy and m is mass.

Front

What is the formula for Work done?

Back

Work done (W) is calculated using the formula W = F × d, where F is the force applied and d is the distance moved in the direction of the force.

Front

What are the units of Work?

Back

The units of Work are Joules (J), where 1 Joule = 1 Newton meter.

Front

What is Force?

Back

Force is an interaction that causes an object to change its velocity, defined by Newton's second law as F = m × a, where m is mass and a is acceleration.

Front

What are the units of Force?

Back

The units of Force are Newtons (N), where 1 Newton = 1 kg·m/s².

Front

What is Momentum?

Back

Momentum is the product of an object's mass and its velocity, calculated using the formula p = m × v, where p is momentum.

Front

What are the units of Momentum?

Back

The units of Momentum are kg·m/s.

Front

What does it mean if an object does 0 work?

Back

If an object does 0 work, it means that either no force was applied, or the object did not move in the direction of the force.

Front

How do you find the velocity of an object using momentum?

Back

Velocity can be calculated using the formula v = p/m, where p is momentum and m is mass.
