Forces and Motion

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction.

Front

What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

Unbalanced forces are not equal and can cause an object to accelerate or change its motion.

Front

What is net force?

Back

Net force is the sum of all forces acting on an object, determining its motion.

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between surfaces.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

What is inertia?

Back

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