Newtons Laws

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its motion. It can make an object start moving, stop moving, or change direction.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other. On Earth, it pulls us down towards the ground, allowing us to sit, stand, and walk.

Front

What is a magnetic force?

Back

A magnetic force is a push or pull that occurs between magnets. It can attract or repel objects made of certain metals.

Front

What is a spring force?

Back

A spring force is the force exerted by a compressed or stretched spring. It can push or pull objects, like when you jump on a trampoline.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its speed or direction. It occurs when an object speeds up, slows down, or changes direction.

Front

What is balanced force?

Back

Balanced forces are equal in size and opposite in direction. They do not cause a change in motion.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or condition. For example, a stretched spring has potential energy.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces in contact. It can slow down or stop moving objects.

Front

What is weight?

Back

Weight is the force of gravity acting on an object. It depends on the mass of the object and the strength of the gravitational pull.

Front

What is the first law of motion?

Back

Newton's first law states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an unbalanced force.
