Force Vocabulary

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

• Newtons first Law

• Newtons second law

• Newtons Third Law

• Gravity

How many laws does Newton have?

• 2

• 3

• 4

• 5

Forces that produce a nonzero net force, which changes an object's motion

• Balanced force

• gravity

• inertia

• unbalanced force

A force of attraction between objects that is due to their masses.

• Gravity

• projectile motion

• free fall

• Newtons first law

Newtons second law states

• Force = mass x acceleration

• For every action there is an equal and opposite reaction

• An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

• Equal forces acting on an object in opposite directions

Equal forces acting on an object in opposite directions

• unbalanced forces

• inertia

• gravity

• balanced forces

projectile motion

• the curved path that an object follows when thrown, launched, or otherwise projected near the surface of Earth

• the constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity

• A push or pull exerted on an object

• A force of attraction between objects that is due to their masses.

Momentum

• The product of an object's mass and velocity

• Equal forces acting on an object in opposite directions

• the motion of a body when only the force of gravity is acting on the body

• The tendency of an object to resist a change in motion

The tendency of an object to resist a change in motion

• Newtons second law

• inertia

• gravity

• free fall

A measure of the gravitational force exerted on an object.

• weight

• inertia

• projectile motion

• free fall
