Forces Review

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion. Unbalanced forces cause an object to accelerate or change its motion.

Front

Energy due to motion is ____________ energy.

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

Which point has the most potential energy?

Back

Point A has the most potential energy, typically because it is at a higher position compared to other points.

Front

What is the matter in an object that affects gravitational forces?

Back

Mass is the amount of matter in an object, which affects the gravitational force acting on it.

Front

What is the sum of all forces acting on an object called?

Back

Net Force is the total force resulting from the combination of all individual forces acting on an object.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two objects with mass, which pulls them towards each other.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as height above the ground.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What happens to an object when unbalanced forces act on it?

Back

When unbalanced forces act on an object, it will accelerate in the direction of the net force.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass, calculated as Weight = mass × gravitational acceleration.
