Forces

Front

What is a Force?

Back

A push or pull that can change the motion of an object.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its motion.

Front

What happens when the net force is zero?

Back

The forces acting on the object are balanced, and the object does not change its motion.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

How does salt affect friction on icy surfaces?

Back

Salt increases friction, helping to prevent slipping.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the Earth pulling us down.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
