Is it Work?

Front

What is work in physics?

Back

Work is done when a force causes an object to move in the direction of the force. It is calculated as the product of the force and the distance moved in the direction of the force.

Front

What is the formula for calculating work?

Back

Work (W) = Force (F) × Distance (d) × cos(θ), where θ is the angle between the force and the direction of motion.

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

Does a stationary object have work done on it?

Back

No, work is only done when an object moves as a result of a force.

Front

Is work done when pushing against a wall?

Back

No, because the wall does not move, even though a force is applied.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses 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 state, such as gravitational potential energy based on height.

Front

What is the relationship between work and energy?

Back

Work done on an object results in a change in energy. Work can transfer energy from one object to another.
