Why is the Equator warmest?

Back

Front

What is Newton's 1st law of motion?

Back

An object at rest stays at rest unless acted on by an unbalanced force (inertia).

Front

What is the formula for calculating force?

Back

Force = Mass × Acceleration.

Front

What is net force?

Back

The overall force acting on an object, taking into account all individual forces.

Front

What does balanced forces mean?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.

Front

What is the unit of force?

Back

Newton (N).

Front

What happens to an object in motion if no net force acts on it?

Back

It continues to move at a constant velocity.

Front

What is the effect of unbalanced forces on an object?

Back

They cause the object to accelerate in the direction of the net force.
