Force and Motion Review

Front

What is the definition of force in physics?

Back

Force is a push or pull acting on an object, which can cause it to accelerate, decelerate, or change direction.

Front

What are the two main types of forces?

Back

The two main types of forces are contact forces (e.g., friction, tension) and non-contact forces (e.g., gravity, magnetic force).

Front

How does gravity affect the motion of objects?

Back

Gravity is a force that pulls objects toward each other, causing them to accelerate towards the center of the Earth or another massive body.

Front

What is motion in physics?

Back

Motion is the change in position of an object over time.

Front

What is the difference between a push and a pull?

Back

A push is a force that moves an object away from the source of the force, while a pull is a force that draws an object closer to the source of the force.

Front

What happens to an object's motion when a net force is applied?

Back

When a net force is applied to an object, it causes the object to accelerate in the direction of the net force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; an object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

How does the mass of an object affect its motion?

Back

The greater the mass of an object, the more force is required to change its motion (accelerate it).

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = m * a, where F is force, m is mass, and a is acceleration.

Front

What is the role of friction in motion?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction to the movement.
